Low-cost devices of 2-4 class are developed from high-quality structural and alloyed steel of different types of protective and decorative coating: nickel, chrome, zinc and nitrite and powder.

Production features

In 1992, the company began to release locking mechanisms in the city of Vyatskie Polyany, Kirov region. All types of devices are created on the basis of modern technologies and world standards in the field of locking mechanisms.

Locks "Mettem" belong to a series of high-strength structures that comply with GOST. The internal elements are treated with zinc galvanizing or created from hardened steel to prevent corrosive formation. Individual elements are equipped with drafts that facilitate lower and upper door closing. About 500 thousand code ciphers provide reliable protection against the selection of skeleton keys.

Types of locking devices

The factory is famous for the production of mortise and overhead locks with protective traps from opening. The product range differs from the models with different number of sovald - from 4 to 10. Separately positioned are the "Mettem" lock-code locks , which include the possibility of locking systems. Installation of lock structures is successfully performed in doors made of wood and metal.

Combined devices are characterized by the presence of two different protectors - a lever and a cylinder.

Cylinder type of protection 2-4 class of safety in accordance with GOST is certified for installation in armored and fireproof doors.

Accessory locks

The access of multi-storey houses, industrial and office buildings is blocked by the common system of use or a separate unlocking device assigned to each owner.

Locks "Mettem" are completed with a limited number of keys. However, the increased risk of their loss affected the creation of code locks with latches ZKP-1 and ZKP-2. They are characterized by identical design features, and the main difference is the thickness of the doors. The first model is suitable for input groups of 24-35 mm thick, and the second one is 40-45 mm.

All movable elements of the mechanical code device are made of high-strength steel. The mechanism for the code set includes 10 buttons. The code can be changed. Partial disassembly will take time, which is unprofitable for the cracker. Code combinations have from 1 to 4 thousand ciphers. Secret latches are often used for locking gated holiday gates.

Radio-controlled protective devices

A consignment or mortise mechanical combination lock is supplemented by an electronic control system, it does not require keys to use it. The control is carried out by the remote key. A spare battery is a battery with a capacity of 2.2 A / h. The battery is designed for trouble-free operation of the mechanism for 6 days. Electron-mechanical devices conquer users with a high degree of protection: the number of code combinations of remote keyfobs is 4 billion ciphers.

Characteristics of overhead locks

Overhead systems are easy to install. They are closed from the outside with a key. From the inside, a turntable is used, which allows them to perfectly cope with their task as a safety net.

Company offers:
