Criteria for choosing a door lock
Choosing a door lock, first of all, attention is drawn to the degree of protection and the secret locking mechanism. And this is correct, because door lock designs provide reliable protection of apartments.
In contrast to obsolete obsolete and overhead locks, the door lock has the highest degree of protection. How should I choose a mortise door lock? Choose a door lock is recommended by some criteria, which can be called the main:
• Reliability
• safety class
• fabrication material
Let's say frankly, a solid and reliable castle is expensive, very expensive. Confirmation of this is the prices for door lock mortise, which is significantly different from the prices for false locks.
Revelations of professional burglars
Modern locking systems by type of secret locking mechanism are divided into the following types:
• cross-shaped wrench
• cylinder
• Suvaldnye.
In order not to leave the slightest chance for burglars, it is necessary to excellently understand modern locking systems or, in simple terms, locks.
cross-shaped locks
Cross-shaped locks or a cross-shaped key are locking systems with a pin cylinder mechanism of a characteristic configuration. The design of the cylinder mechanism has a row arrangement of the pins. In each row of the design, more than two code pins are possible. The well for the key in cross section has a cross-shaped shape. Cross type locks are designed for installation in metal entrance doors in two versions: mortise and insert.
Equipped with cylinder locking mechanism, the pins of which have small dimensions and are located in three planes in a circle with an angle of 120 degrees.
However, this type of locking system has a low degree of secrecy and that the most insulting is a low degree of burglar resistance. The security class of cross-shaped locks is low - 2. A primitive cross-head screwdriver can become a method of breaking into this type.
The cracking of the cruciform castle is primitive and the time of silent resistance to professional burglars is 1 minute. The burglars do not even need to drill a secret and bumping. Bumping - a method of opening the burglars lock and pin cylinder.
So, before it's too late, change this lock to install a different type of mortise lock, for example, a cylinder lock or a lever lock.
cylinder locking mechanism
The competitive market for locking systems production required innovative finds and solutions. Therefore, the full cylinder mechanism provided new solutions, namely the cylinder Mul-t-lock.
What is the cylinder locking mechanism and what is the secret of its mechanism? We'll talk right away, the whole secret lies in a removable cylinder with a variety of cuts.
A series of rifling cylinder mechanism can be represented by:
• for finger pins
• for telescopic pins
• for the locking bar in the form of "snake"
• with a unique active locking element
• in the form of a floating steel element at the end of the key.
Types of cylinders are represented in the form: cylinder key-key; cylinder key switch.
Cylinders of locking system with reinforcement on the body are manufactured by the manufacturer in several versions:
• with the strengthening of the body (larvae) from any mechanical damage, including drilling, biting, knocking out and turning
• with a sliding beard made of hardened steel and hard-alloy pins.
In addition to the above advantages, the cylinder locking mechanisms have a sufficient total diameter of the pins, which exclude the possibility of dissolving the lock with acid or "rolled up". Therefore, the lock of the door mortise cylinder can be called the "right" choice.
The safety class of cylinder locks is high - 4.
lock locks
The lock locks can be imagined in the form of a powerful guy with "pumped" bolts, which "crouching to the intellectual" cylinder cylinder leniently provides a head start, feeling its obvious advantage. It is the arms, which are a package of plates with a complex configuration, forming a groove into which the entire crossbar plate moves.
The most common designs of lock locks have a slot that allows the driver to occupy a strictly defined position. Mortise locks Suvald type is currently equipped with a set of sovald, providing the ability to quickly replace the entire locking mechanism.
Often two keys with a secret are used for the key of the lock. This allows you to increase the privacy of the system. Unlike the cylinder lock, which has a replacement larva, in the lock lock it is necessary to reprogram the gears, changing them by places. Therefore, the safety class of lock locks is high, starting from 4.
Installing a Mortise Lock
Installation of the mortise lock can be successfully carried out independently.
Before installing a mortise lock of any type, make measurements of the thickness of the door leaf. The recommended thickness of the door leaf should reach a thickness of 40-50 mm. The height of the installation is 1/3 of the height of the entrance door. To install a mortise lock of any type on the entrance door, a landing hole or socket is made.
In parallel, a latch hole is made in the door frame. The lock is inserted into the prepared hole in such a way that it is possible to hold it by the latch. Securely fasten the lock by removing excess material from the cover and the front of the new lock case. If there are armored plates in the delivery set of the lock, then install them according to the manufacturer's instructions.
The locking plate is mounted on the door frame according to the preliminary marking. The locking plate must be secured with self-tapping screws. Installing the mortise lock, make adjustment of its operability. To do this, make several control openings and closings of the installed lock and you can enjoy peace and security.
