The main guarantor of the safety and reliability of your property is a door lock. You can only entrust this mission with a high-quality castle that has the appropriate certificates and a certain protection class made of durable materials. Choosing it right is just as important as getting a good door.
There are different types of locks. The most common of them are divided into overhead and mortise. The former are rarely installed on metal doors, since they do not look very attractive from the inside. These locks are ideal for wooden doors, they are easy to operate and install. Mortise locks are both protection and fastening, aesthetically look good, are installed by inserting or inserting into the door.
The following types of door locks are distinguished according to the mechanisms of action: crossbar, code, electronic, level, cylinder. Let's consider them in more detail. Crossbar types of locks represent protection of a door not at one, but at several points. They fix the closed door due to locking mechanisms (the main one is a spring-free deadbolt).
Combination locks let us not worry about keys. They require very careful layout. In a good electronic lock there is a drive that manages the deadbolts. His "key" and
the control unit should not be combined. The door itself with such a lock does not have any markings. When disconnected from the power supply of the lock, it must remain closed. The lever types of locks are classic locks that have an internal massive part and a system of special code plates. It is hard enough to crack such a lock physically, but there is a high probability that an attacker will pick a master key.
Cylinder locks are characterized by easy replacement of the mechanism in the lock. The key can determine the mechanism of secrecy. The most common are disk and font privacy mechanisms. These types of locks have a rather complex shape with a large number of holes and cutouts, are one-sided and two-sided. The more complex shape of the key determines the higher security of the lock. This castle was invented not so long ago - about 150 years ago. Due to the high degree of reliability and protection, it is almost impossible to pick a master key for it.
In addition to door locks, there are also padlocks. In turn, there are various types of
padlocks. If you classify them by size, you can distinguish small (miniature) locks (used for constipation of modern suitcases, mailboxes, collars for large dogs), medium (general purpose), large (for different household needs), granary (for warehouses and sheds) . According to the design features, padlocks are classified as secret, screw, code, level, non-lever and on the basis of cylindrical mechanisms.
Now that you know the classification and varieties of all existing castles, you can safely go to the store. It is very important to choose locks that will meet your needs and requirements, and most importantly - to protect you reliably.
