Even the most good doors Over time, they may begin to creak or sag: no one can cancel the force of gravity and friction. And if you have heavy steel ones, then even the metal will get tired of holding them. After the summer, plastic ones also “sag” - they almost always remain open in the heat, which leads to such results. There is no need to tolerate these “disgraces,” nor is there any need to spend money on eliminating them. Although adjusting the entrance doors is a delicate matter, in most cases you can do it yourself. Once you have adjusted the hinges and the rebate with your own hands, you can easily repeat it later.
Adjusting a metal entrance door
- creak;
- draft - blowing from under the canvas (cracks around the perimeter or from above/bottom);
- closes with difficulty.
The solution to all these problems is called "adjustment" front door“, but this includes very different measures - from banal lubrication and replacement of the seal, to actual adjustments and mechanical influences.
Sometimes, to fix a problem, you need to go through all the methods, and sometimes the problem that has arisen can only be eliminated radically - by replacement. Most often, this situation occurs with cheap Chinese products. Adjusting entrance doors made in China practically impossible. Of course, you can try to do something with your own hands: companies and craftsmen do not undertake them.
Eliminating the squeak
Doors can creak for two reasons: the hinge grease is clogged or door leaf hits the frame. Although both are called “creaking”, the nature of the sound is different. It’s easier to deal with clogged loops, so they usually start with this procedure.
Hinge lubrication
First, remove the old grease, at the same time removing any dirt stuck to it. The procedure is standard: wipe with a soft cloth wherever marks are visible. If this procedure They haven’t done it for several years, but the hinges are of the standard classic type, and even detachable, the fabric can be removed. It is better to clean it when removed.
If the hinges are rusty and cannot be removed even though they should, do not try to knock them off with a hammer or sledgehammer. You'll do more harm than good. It is better to buy a rust remover. It is usually sold in the form of sprays. Apply to the rusty hinge and wait deadline. Then remove the fabric from the loops and clean it. But this time it is necessary to remove all the rust. To bare metal, then coat with rust converter and only then with lubricant.
After the old lubricant is removed, take “fresh” and apply it to the hinges. If the blade is removed, no problems will arise - lubricate the pin and ring. If there are any other rubbing mechanisms visible on the frame, lubricate them too.
In the loops traditional type The creaking may occur due to the fact that the washer on the rod has worn off. You inspect it after you have removed the door panel. If there are signs of wear, replace them. Install a new carbide washer. You can use an engraver instead. It will also compensate for the load.
If the hinges are permanent, find a liquid lubricant in a can (the most common is WD40) or machine oil, which can be applied using a large syringe. Handle all rubbing parts carefully.
There is another method, but it is destructive. A hole is drilled in the upper part of the loop, which is then filled with lubricant. The trick is to not damage the mechanism inside.
If the hinges are hidden, find all the turning parts and lubricate them. Often these models have holes into which oil is applied.
After applying the lubricant, rock the doors from side to side several times, distributing the lubricant. If this was the reason, the squeak goes away. Finishing touch- wipe off excess oil.
How to lubricate front door hinges
You must select a lubricant primarily based on the temperatures at which the loop is operated. If the loops go outside, you need a composition that does not thicken when low temperatures. There's not much choice here:
- Litol. Operates reliably at temperatures from -40°C to +120°C.
- Solid oil. Temperature range a little lower, but also sufficient: from -35°C to +65°C.
For entrance doors facing the entrance and operated at above-zero temperatures, several more items can be added to this list:
Eliminating friction on the box
If the creaking remains after processing the hinges, it is most likely caused by friction of the door leaf against the frame. Inspect the door frame for scuffs. If you find any signs of abrasion, look at which loop is closest. It will need to be regulated, if possible.
The difficulty is that there are a lot of types and models of loops and it is impossible to say unambiguously what needs to be done. All that is possible is to list the main points that may exist. Based on them, you may be able to determine how to “treat” your door.
Two types of loops for the entrance metal door with adjustment
Standard hinges do not provide adjustment options. In this case, adjusting the entrance doors consists of replacing the washer. Select them of greater or lesser thickness, adjusting the position of the door leaf. Some hinges with a ball at the top have an adjustment screw. By unscrewing it, we lift the doors a little, and by twisting it, we lower them. You can try to correct the situation with its help.
If standard hinges are on steel door welded, we can assume that the possibilities have been exhausted. If they are mounted on screws, the fastening screws are loosened and the sash moves into in the right direction as far as possible. Then the screws are tightened. Check to see if the problem has gone away. If not, try with another loop. Sometimes it is necessary to loosen all the loops and tug the canvas in this position. In general, decide where to press and where to press.
There are hinge models in which the adjustment holes are hidden under a protective cap. But you can’t just remove it: it is secured with a bolt that can be unscrewed from inside the room. An example of adjusting such a loop is in the video.
If the hinges on the front door are screwed on, you can use them to eliminate friction between the door leaf and the frame. First, loosen the screws near the area where the wear occurs. Try to move the door leaf a little. To begin with, you can knock with your palm or fist, moving it in the desired direction. Try opening/closing a couple of times. Did it help? Screw the clamping screws back. And try to open/close again.
If it doesn’t help, you can use some kind of leverage, hit it with a rubber mallet or hammer through the board. But don't overdo it. You need to handle Chinese products especially carefully: they are very flimsy.
If these manipulations also do not yield anything, you will have to loosen the screws on all the hinges and try to move the canvas over the entire area. Take the edge of the canvas with your hands and shake it. In this case, the loops should fall into place. You try to open and close. If there is no squeak, tighten the bolts. That's all, adjusting the front door hinges can't do more. The next thing you can try is to change the geometry of the door frame. More on this in the next paragraph.
The photo above (right picture) shows an adjustable hinge. By loosening the screws, you can turn the adjusting screw. It doesn’t help - we try to move the canvas as described above.
Eliminating a leaky door (blowing from under the door)
Sometimes there is a noticeable blow from under the front door. If you examine the perimeter, you will most likely find that in some place the fit of the door leaf to the door frame is loose. There may be a decent sized gap. You can check your suspicions with a piece of paper. Open the doors, insert a piece of paper between the door leaf and the jamb and close the doors. If the rebate is normal, the paper either stretches with very great force, or is clamped so tightly that it is impossible to remove it. Just break it up. If the sheet comes out freely, then the fit is insufficient.
The simplest explanation is that the seal has lost its elasticity. If the doors are several years old, this is possible. And the first thing you do is change the seal. Didn't help or only partially solved the problem? Let's move on.
Replacing the seal is the first step if there is leakage from under the front door
If the door leaf is displaced relative to the door in the horizontal plane, we try to eliminate the draft from under the front door by first moving the door leaf. This is described above: loosen the fastening screws on the hinges, then try to move the blade in the desired direction. Check the result - the gap has disappeared - tighten all the screws to their original position.
Sometimes gaps under the front door occur due to misalignment of the door frame. This is checked using a level. Most likely, it is skewed in the place where the sheet of paper can be easily removed. The second option, on the contrary, the box was pushed out in the place where the sheet is pressed, due to the fact that the “normal” part cannot be pressed. All this is determined using an eye gauge and a level. Having determined what the problem is, we try to return the geometry to normal. The measures depend on how the box is installed:
For an option to correct the gap in the vestibule, see the video. After entrance door installation It turned out that it was blowing strongly from under it. The owner corrected the distortion with a hammer.
Eliminating door sag (shuffles on the threshold)
If, after several years of operation, the doors begin to open with difficulty and rub against the threshold, most likely the problem is that the ball or bearings have worn out. If there are possible adjustments, you won’t even have to remove them. Simply unscrew one of the bolts and lift it slightly up.
If there is no adjustment, there are several options:
- replacing hinges;
- replacing bearings with new ones;
- installation of washers instead of bearings.
All this is determined based on the situation and the design of the loop.
Adjusting plastic entrance doors
The problems may be the same: friction, creaking hinges and loose connection to the frame, which can cause blowing. But door adjustment PVC is easier— hinges and mechanisms are standardized, there are not many types. So there is hope that you can deal with the problems yourself, without calling a specialist.
Balcony door adjustment
After summer plastic doors they sag on the balcony: in the summer they often remain open for a long time, which is why such a nuisance happens. Then they touch the threshold, it sounds unpleasant sound, the plastic wears off. In this case, you need to lift the canvas up. This is done using the adjustment located at the top of the lower hinge.
They do this when open lock, but the door is closed. Take a hex wrench (usually 4 or 5) and insert it into the hole and turn it a few turns. There is no need to lift too much right away, as this can cause other problems. Raise only until the problem is fixed.
Sometimes, when closing, the doors rub from the side, hitting the metal latches. It turns out that you need to move the canvas towards the loop part. For this there is another adjustment on the same hinge. It is located below, visible when the door is open.
This adjustment is also carried out with a couple of turns clockwise or counterclockwise. If you need the doors to not rub against the counter, turn counterclockwise. Give it a couple of turns and check. Once the problem goes away, stop. Otherwise, you can move it so much that the lock stops “clinging” to the mate.
If the upper left corner “clings”, you need to adjust the loop that is located at the top. The principle is the same: one or two turns until the problem is eliminated.
Top Hinge Adjustment - Top Left Corner Pressure
Pressure adjustment (to prevent draught)
Sometimes weak pressure is observed from the side of the locking part. It seems that the canvas adjoins smoothly, but there is a noticeable pull from under the door. In summer this is not a problem, but with the onset of cold weather it significantly reduces the temperature. There are two ways. The first is to adjust the clamping pins. These are metal protrusions on the sash.
They come in two types. as in the photo above - oval and round, but with an eccentric in the middle. The position of this element determines the degree of pressing of the sash to the frame. The method of changing the position depends on the shape of the trunnion. If it is like in the photo, take pliers, clamp it and turn it slightly. The maximum pressure is if the long side is turned horizontally, the minimum is if it is directed vertically upward. There are also all the intermediate options.
If there is an eccentric in the center of the trunnion, then there is also a hole for the hexagon. Insert it and turn it, achieving the desired degree of pressure.
It is not recommended to set the stasis to the maximum value: the seals will quickly lose their elasticity. Also make sure that all eccentrics are rotated the same way. This guarantees normal operation of the fittings.
But sometimes there is a situation where the sash is not pressed tightly balcony door from the hinge side. This can also be eliminated by adjusting the hinges. At the bottom it is located under a protective cap. Remove it (pull it up). Take the key (hexagon) and with a couple of turns adjust the clamping of the lower right corner of the plastic balcony door.
Also available on frame hidden hinges, which also include the ability to adjust the pressure. They are located on the frame on the hinge side. Adjustment with the same hex wrench. Turns “clockwise” and “counterclockwise”.
Adjusting plastic entrance doors
The plastic entrance doors have different hinges, and there are no locking and tilting fittings. They have closed loops of the overhead type. They have three adjustments:
- the height of the door leaf relative to the frame - at the bottom of the hinge;
- the density of pressing the canvas to the frame is on the top on the hinge;
- sash movement horizontally - sideways
They are sufficient if the doors were initially installed correctly: the limits for changing positions are significant, which makes it possible to compensate for those changes that occurred during operation.
If there is a squeak in the hinges, they need to be lubricated. To do this, remove the top cap and put lubricant into the opened hole. Since plastic doors are installed as entrance doors mainly in private houses and they go out onto the street or into an unheated vestibule, you select a lubricant that does not thicken at low temperatures (Litol and Solidol).
Put lubricant here
In some models of hinges, the lid is simply lifted off, in others, you need to unscrew it and then pull it out. Determined by location.
Sometimes a situation arises when intervention is required: the lock does not lock properly. If the sash pressure is normal, correction of the striker is necessary. She is mobile in such doors. Loosen the mounting screws, use a screwdriver to move the bar slightly in the desired direction and tighten the screws back. Checking. It should help.
of us when moving and renovating a new house or apartment. The procedure of reassembling old hinges itself is required if it is not advisable to purchase new hardware elements. IN in this case We will consider the parsing procedure in detail using an example door hardware Archie, which already has a lot of fans among repair and construction organizations due to the ease of installation and subsequent operation of the door leaves.
Appearance and design of the butterfly door hinge
It is worth noting that in this case we will consider the procedure for disassembling a butterfly loop, which is only suitable for interior doors. It is unreasonable to use such hinge models for an entrance door due to their simplicity and unsuitability for massive panels that are installed on entrance groups.
Before you begin work on disassembling the universal hinge, you should perform a number of preparatory procedures, namely:
Drawing with dimensions of a universal butterfly loop
On this initial stage repair or maintenance work ends, and you can begin to diagnose faults and then eliminate them.
It is worth noting that the hinge plate may contain additional decorative trims, blocking access to screws or screws. Before dismantling, they should be carefully removed. You will also need to first unscrew the screwed-in awnings, which are used as a lock to remove the interior door leaf.

Troubleshooting
After everything structural elements removed, you can begin troubleshooting. To do this, perform the following series of actions:
- mortise hinges are assembled into a single mechanism so that the rotary axis rotates around this axis;
- further, rotational movements check for free play of the pin in the groove;
- after this, the loop should be visually inspected for mechanical damage and cracks;
- As soon as a malfunction is identified, it should be eliminated;
- If there is serious mechanical damage, the product will no longer be repairable and it will be much easier to purchase new hinge mechanisms.
If the overhead internal fittings are not damaged, and the problem is that the pin moves too tightly in the groove, then the groove should be filled with a special lubricant, which should also be applied to the pin itself. It is worth noting that only material that does not have a detrimental effect on the metal can be used as a lubricant. Otherwise, you risk having to quickly replace the hinges or repair them.
Troubleshooting
If a visual inspection reveals minor mechanical damage, such as:
Various colors of butterfly loop
- deformation of the metal pin;
- small crack in the groove;
- small crack in fasteners.
You can easily fix these problems yourself. To do this, disassemble the door hinges, carefully align the pin using a hammer and pliers.
Scheme of fastening the door to a butterfly hinge
If the problem is hidden in minor damage, then you can use instant glue and sealant that will reliably join the damaged parts. It is worth noting that even a slight deformation of the pin can lead to incorrect operation of the entire hinge group, so when performing a visual review of the product, pay attention special attention exactly on the pin.
Installation of hinges and door leaf canopy
After the faults have been fixed or new ones have been purchased door hinges, you can begin installing the fittings in their original place of attachment.
The process of installing a butterfly hinge on a door
To do this, perform the following step-by-step procedure:
It is worth noting that it is much better to place the mating parts of the hinge groups with pins on the door leaf, otherwise you will have some difficulties when hanging the door.
An example of attaching a butterfly door to a door
Once the entire procedure is completed, the entire product should be checked for functionality. To do this, open and close the door several times. 
Important. Hinge groups of card models are used only for doors interior type, also when purchasing such fittings, you should pay attention to the material from which they are made, since these models of hinge groups are not suitable for installing a door heavy weight, due to fragility components loops.
The video shows how to eliminate sagging butterfly hinges.
The question of how to adjust a metal entrance door can sooner or later concern everyone. To avoid problems and hiccups, in our article we will look at all aspects of solving this problem.
Proper adjustment will help extend the life of the door
When to make adjustments
When might it be necessary to make adjustments to the door system? The first thing you need to do is set the appropriate parameters during installation. The weight of the web should be evenly distributed over the fastening, if the mass does not match and the maximum permissible load on metal elements the design loses some of its functionality, gradually loosens, which can lead to jamming of the lock, increased friction between parts and its complete breakdown.
When the seasons change, the position of the metal entrance doors should be adjusted; this can easily be done with your own hands: in the winter the porch is made tighter, and by summer it is slightly weakened. Must be carried out regular check system and, if there is the slightest defect, fix the problem, this will significantly extend its service life, which is very important for the front door.
Discomfort when using the front door is most often eliminated by adjusting the hinges
In order to acquire the skills necessary in everyday life, you must first figure out how to adjust the metal entrance door in the following cases:
- A squeak is heard when the door moves. The reason may be the ingress of dust and other contaminants; sometimes a squeak occurs when the sash is rubbed against the frame.
- Doesn't close well, doesn't fit tight. This defect occurs when the position of the locking tongue and the hole for its entry do not match, there is misalignment, or the thickness of the seal is large.
- There is a gap between the canvas and the box. The reason often lies in the wear of the seal, as well as the misalignment of the locking plate antennae.
Required Tools
Do-it-yourself adjustment of aluminum doors is done using the following tools and materials:
- hex wrench;
- socket wrench;
- file;
- oil for lubricating parts;
- screwdriver;
- seal.
The necessary set of tools for repairing a metal door
Basically, all work is done using keys, especially if the cause of the problem is a misaligned door diagonal.
Creaks
Creaking is the most common problem associated not only with entrance doors, but also with other structures. The main reasons are the lack lubricants, rubbing of mechanism parts, getting inside fine particles foreign substances. In this case, it is enough to clean the system and lubricate all the internal parts that fit together, especially the rotating mechanism.
The very popular WD-40 spray can help quickly get rid of door squeaks.
Also, a similar problem can be caused by the displacement of the canvas, as a result of which its edge begins to touch the box. This is quite easy to detect - traces remain at the site of friction. How to adjust the input in this case? iron door? Using a wrench of a suitable size, you need to slightly loosen the hinges near which damage to the box is noticed, then move the blade closer to the mount, tighten the adjusting nuts until they are in their original place. Check whether the expected effect has been achieved. If necessary, the operation is repeated until the squeak disappears.
If the door leaf is displaced, adjusting the hinges can solve the problem.
tight narthex
Basically, such a defect occurs for two reasons. Let's look at how to adjust a metal door separately for each specific case:
Large seal thickness. Entrance doors must be equipped with a special rubber band that seals the seams and closes the gap between the door leaf and the frame. Most often, the problem of a tight shutter is encountered by owners of new, recently installed doors. The fact is that the rubber band has not yet had time to spread, and therefore can complicate closing the door. The rational solution is to wait; over time, the seal will develop, shrink slightly, and the problem will solve itself. Under no circumstances should you cut the elastic, because after a few weeks it will sag and a gap may appear in that place.
A tight seal may be caused by a new seal that has not yet been developed
Mismatch between the tongue and the plate. In that case locking mechanism touches the plate and hardly fits into the recess. This defect is not uncommon for cheap models; the problem can be solved with the help of a file. It is necessary to carefully grind off the excess metal on the plate so that the tongue passes freely inside, but at the same time securely holds the door in place. closed position. If the metal can be bent, try straightening the tendrils using pliers.
The problem may arise in the area of the locking mechanism
Big gap
The complete opposite of the previous defect is an overly wide shutter. Even in a fully closed position, there remains a gap between the door and the hatch. The main cause of this problem is the thinning of the seal during prolonged use. If this is indeed the case, the rubber band needs to be replaced. Before gluing a new tape, make sure that the gap around the entire perimeter is the same; if there are places where it is wider, you need to use an additional lining.
Often the problem of a large gap is solved by replacing the old, thinned seal with a new one
Another reason could be a similar defect, as with a tight shutter. How to adjust backlash aluminum door when the tongue and the bolt entry hole do not match? In this case, you need to bend the antennae of the plate to a position that will ensure a tighter fit of the door to the frame. Less often, the situation can be corrected by adjusting the tension by tightening the loops. From time to time it is recommended to check the position of the door and adjust it.
Regularly renew the lubricant, this will extend the service life of all structural parts.
Timely adjustment of metal doors done by yourself is the key long service structures, protection against breakdowns and ensuring safety for all residents of the house.
The popularity of entrances is growing every day. When choosing inexpensive budget models, consumers are faced with incorrect operation of the product. It is caused by both and other factors - shrinkage of the new building, manufacturing defects or design flaws. Therefore, the selected and installed model will have to be adjusted correctly.
Additional adjustment of the metal door
More often than others, Chinese metal entrance doors require additional finishing.
In order for the design to work flawlessly, it is necessary to eliminate the detected deficiencies in a timely manner:
- tight pull - the door does not close well and the handle is difficult to turn
- creaking when the blade moves
- the gap remaining in the closed position between the box and the canvas
How to adjust a door with an incorrect opening
The reason for the incorrectness is the part of the door leaf protruding beyond the door frame.
A door with a rebate fits into the frame, covering it from the outside with its part protruding beyond the dimensions of the opening. Due to this, the reliability of the design increases, including a metal protrusion, which makes it difficult to break into.
Loose fit of the vestibule to door jamb, which Chinese entrance doors sometimes suffer from, is caused by several reasons:
- Recently installed structure- due to a new seal that has not yet gotten used to it. After 2-3 weeks of work, the problem will disappear on its own.
- Incorrect entry of the tongue into the key hole on door frame. To fix the problem, find a thin plate bent inward on the bar into which the tongue fits. By slightly bending or bending it, the tightness of the door closure is adjusted.
- A manufacturing defect, when the inlet hole for the bolt and tongue is shifted or is smaller than required. In this case, the hole is corrected using a file.
- A very light rebate indicates that the seal has become thinner, for normal operation replacing it is enough.
What needs to be done to prevent the door from squeaking
Adjust Chinese door To eliminate squeaking, you can do it the same way as any other model.
An unpleasant sound when opening or closing a suspended structure. You can eliminate the squeak by cleaning and lubricating the hinges or eliminating friction between the blade and the box. In both cases you need to adjust the hinges. To work you will need tools:
- slotted and Phillips screwdrivers
- end or
- hex heads
- hinge lubricant.
Metal doors that produce an unpleasant squeak are examined in the following sequence:
- The product is opened slightly and the fasteners are loosened first on the middle ones, then on the remaining hinges.
- The canvas is pulled towards itself several times, then tilted back towards the jamb.
- To properly fix the loops, the canvas needs to be shaken a little.
- If the creaking is caused by friction inside the hinges, they are blown out with a compressor and lubricated. Machine oil is used for this. The WD- aerosol product will quickly help get rid of squeaks.
- If an unpleasant sound occurs due to friction of structural parts against each other, it means that the door is skewed and needs to be returned to its original position. normal position. To do this, you will again need to adjust the hinges. Use a suitable key to loosen them or tighten them until the door leaf is level and the friction of the parts, and therefore the creaking, stops.
Self-adjustment of a metal door
The adjustment is carried out in several stages to eliminate all possible reasons incorrect operation of the structure:
- faulty door closer
- lock
- loose fittings or awnings
- poor sealing material.
Adjusting the door closer
The smoother the closer moves, the easier it is to use the door. The mechanism of the device, which is installed instead of the spring, may be to blame for the fact that it opens poorly or does not close completely.
- To change the door closing speed, the existing control valves are turned.
- The tension of the closer is adjusted with a special nut by turning it in the direction of tightening or loosening the tension.
- To prevent sudden opening of the canvas, the adjusting nut is tightened counterclockwise. This will reduce the opening angle.
Adjusting and cleaning the locking mechanism
If the adjustment in the indicated ways did not lead to desired result maybe the reason improper work door design imprisoned in a castle. In order for it to work properly, it must be maintained in working order by lubricating and cleaning. To remove accumulated dirt from the mechanism, you can use the popular Lock spray or Lock kleaner.
- A certain amount of cleaning agent is sprayed into the keyhole so that it flows out a little.
- Insert it, and then, without turning it in any way.
- Wipe the key with a clean rag and repeat the procedure until no more dirt appears on the key.
- Inject lubricant into the key hole, insert and remove the key 2-3 times, and then turn it in different directions several times.
Adjusting hinges on an iron door
If the canvas rubs against the platbands, you need to move it slightly away from the box by adjusting the position of the hinges. To do this you need:
- Loosen the fasteners on the hinge located next to the friction point.
- Use a screwdriver to move the hinge to the side to create a small gap.
- Secure the position with fasteners, press down and carefully close the door.
- If there is no more friction, securely fix the loop in this position.
- If friction occurs elsewhere on the web, the operation is repeated until the desired result is achieved.
Getting rid of drafts
If cold air blows from under the door and it no longer fits tightly to the frame, then it is time to replace the seal, which is always present in the iron structure.
You can purchase sealing tape at any hardware store. Having removed the remnants of the old material, a new seal is carefully glued in its place.
To reliably protect your home and serve you for many years, it is necessary to eliminate the problems noted in the work of the structure in a timely manner. It is better to spend some time on preventive maintenance than to completely replace the entire structure.
Sooner or later, the front door may begin to creak, sag, and let in drafts. Most often this is due to reasons such as:
- expiration of the door's service life;
- poor quality door;
- errors during the installation process;
- shrinkage of the house;
- failure to comply with the rules for operating the front door.
For example, the door hangs if children ride on it. Sometimes the doors crack nuts. Or they clap demonstratively with such force that the windows rattle. All this is reflected in operational characteristics. Creaks, cracks and other troubles may occur.
Let's figure out how to adjust the metal entrance door in all of the above cases.
Adjusting metal entrance doors for squeaks
Even quality doors may require adjustment during operation. You can do this yourself using a simple set of tools. If you don’t have the time or desire to work on the front door, contact the service department. Professional craftsmen will adjust the door and eliminate the cause of the defect.
