A door lock is an integral part of any door. They are installed in wooden, metal, plastic, glass structures. Regardless of the model, cost and type of door, a lock in it is necessary to protect against intruders. Selection criteria, as well as reviews on door locks will help to buy a high-quality and reliable product.
The classification of door locks is carried out according to two signs - this is the installation method and the type of mechanism.
According to the method of installation in the door, the locks are divided into three main groups:
Mortise locks - the most common option. They have high reliability, as well as excellent aesthetic qualities, as the lock is mounted inside the door.
Overhead locks - easy to install and do not violate the strength of the door itself. If a malfunction occurs, they are replaced very quickly, and they can also be easily repaired.
Padlocks - they are hung on hinges that are attached to the door leaf and to the jamb on the inside of the door. Constipation is presented in the form of a horizontal bar. Such locks are considered reliable against opening from the outside.
After you decide on the model of the lock by the installation method, consider the types of secrecy mechanism.
Privacy mechanism - This is the main part of any castle, which provides protection against hacking. It can be level, cylinder, disk or electronic.
1. Cylinder locks are by far the most popular, although they appeared not so long ago. The cylinder mechanism has high secrecy, but a professional can easily open it. Also, the cylinder is quite simple to knock out of the lock. When buying, pay attention to the number of pins.The larger their number, the more reliable the lock.
2. The disk lock is a type of cylinder lock and has higher safety indicators. Its weak point is the protruding cylinder.
3. Level locks are considered the most reliable, they are much more difficult to crack than cylinder ones. When choosing, you should look at the number of levers, the more there are, the more reliable the lock. However, there are restrictions on the thickness of the door leaf.
4. Combination locks can be mechanical and electronic. In the first case, the code is manually dialed, and in the presence of an electronic mechanism, a special key is used. The reliability of such locks is high due to the lack of a keyhole, which is usually the most vulnerable spot in these structures.
