The moving mechanisms of the door leaf may fail over time or break down. Most often, the door thus changes its position in space and begins to sag. In this case, it is necessary to pay attention to the state of the loops. Why do doors most often sag?
It often happens that the number of hinges does not match the weight of the door, and it sags. Usually this is typical for entrance doors. To remedy the situation, it is necessary to install a third additional loop, preferably 20 cm from the old loops.
If the installation of the front door was not carried out correctly, then the door leaf can be deformed and take a different shape, the mass of the door also contributes to this, the leaf will very quickly begin to sag. This usually happens in the first months of operation.
If the doors are not serviced regularly and the hinges have not been oiled for a long time, then the drawdown of the door may indicate wear of the hinge core. In this case, the regulation of the blade will not work, you must either change the door or hinges.
Also, cheap door leaves that are most prone to deformation sag in the first 10 months. If the door was not installed correctly, then it will begin to sag anyway.
What to do in case of a sagging door
First you need to check the condition of the door hinges, if their fasteners are loose, this will be noticeable visually. To correct them, it is necessary to raise the canvas and tighten the screws. Often this is enough. It is worth noting that the method is only suitable for removable hinges.
All hidden hinges have adjustment mechanisms with which you can align the door leaf. Usually they are fixed on five screws, each of which is responsible for its function. All information about them should be spelled out in the technical passport.
In general, the process looks like this: at first all five screws are loosened, after folding they are brought to the required position, the screws are tightened, and quality control is done. After that, you can adjust the specific screws to align the door.
What to do with worn out loops
Erased hinges do not always need to be replaced, since they are usually worn off at the contact areas of parts. To fix this, you can put a washer or ring of wire under the top of the loop.
Modern hinges are equipped with bearings, and if such problems occur, you just need to replace it with a new one. Such loops last longer than usual.
