The lock is a real "guard" of the door, providing protection. The safety of residents at home depends on its reliability and quality. Today, eyes run up from a large selection of locks, which differ in the design of the locking device and functionality. Let's take a closer look at the crossbar locks.
At the very beginning, they were installed on burglar-proof safes. Over time, such models began to be actively used for roller shutters and metal doors.
Latch locks, as the name implies, provide locking with special pins. The crossbar is a metal detail which is in a door leaf. When you turn the key, it is inserted into the hole located in the door frame. At the same time, the doors are closed “tightly” in each direction: to the sides, down and up.
Overhead bolt locks are best installed by professionals, since various factors must be considered. So, for its installation should calculate the number of installed pins. In order for the crossbar locks to work qualitatively, you should choose the right manufacturing material. In addition, the doors equipped with them must have a special anti-lock system.
Dead bolt lock
This is the best way to increase home safety. In the installation, it is more complicated than the overhead, while more aesthetically pleasing due to the lack of various protruding parts and has higher reliability.
Mortise mortise locks are universal, they are installed in wooden, metal, as well as armored doors. Their main advantage is invisibility. The next important quality is the crab locking system - the tongues of the lock mesh along the perimeter of the entire door: at the lower, side and upper ends, which increases resistance to burglary and locking properties.
The reliability of such models is also due to the fact that they are located in the door leaf, which serves as both a fastener and protection.
Mortise crossbar locks can be locking, locking-locking, as well as locking.
Padlocks
As a rule, padlocks are used for utility rooms, garages and storage rooms. In addition, they are used in swimming pools or in the locker rooms of fitness clubs. They are simple to install, and their weak point is poor security against hacking in comparison with other types of locking devices.
A wide selection of such models is presented on the market today - from the most inexpensive and simple options made of brass or cast iron to the expensive ones made of stainless steel.
Before you get such a lock, you need to consider what type of door it is selected for. The choice of locks must be carried out, starting from the material from which the entire structure is created.
If we touch manufacturers, then at the moment there is a huge selection of locks created by all kinds of manufacturing companies around the world. In general, the choice of device depends on your needs and financial capabilities.
