Locks "Mettem" - domestic products used for reliable protection of apartments, garages, offices, porches and safes. Inexpensive class 2-4 devices are developed from high-quality structural and alloy steel of various types of protective and decorative coatings: nickel, chromium, zinc and titanium nitride and powder.

Production Features

In 1992, the company started producing locking mechanisms in Vyatskiye Polyany, Kirov region. All types of devices are based on 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. Internal elements are zinc plated or hardened steel to prevent corrosion. Separate elements are equipped with rods that contribute to the lower and upper closing of the door. About 500 thousand code ciphers provide reliableprotection against the selection of master keys.

Types of locking devices

The plant is famous for the production of mortise and overhead lever locks with protective traps against opening. The product range is distinguished by models with a different number of levers - from 4 to 10. The lever-combination locks "Mettem", including the possibility of blocking systems, are positioned separately. The installation of lock structures is successfully carried out in doors made of wood and metal.

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

Cylinder type of protection 2-4 safety class according to GOST certified for installation in armored and fire doors.

Passway locks

Access installations of multi-storey buildings, industrial and office buildings are blocked by a common system of use or a separate unlocking device assigned to each owner.

Mettem locks come with a limited number of keys. However, the increased risk of losing them influenced the creation of combination locks with latches ZKP-1 and ZKP-2. They are characterized by the same design features, and the main difference is the thickness of the doors. The first model is suitable for entrance groups with a thickness of 24-35 mm, and the second - 40-45 mm.

All moving parts of the mechanical encoder are made of high strength steel. The mechanism for dialing the code includes 10 buttons. The cipher can be changed. Partial disassembly will require time, which is disadvantageous forburglar. Code combinations number from 1 to 4 thousand ciphers. Secret latches are often used to lock country gates.

RC Protective Devices

The overhead or mortise mechanical combination lock is complemented by an electronic control system, no keys are required to use it. The control is carried out by a remote control. A battery with a capacity of 2.2 A / h acts as a spare power source. The battery is designed for uninterrupted operation of the mechanism for 6 days. Electronic-mechanical devices captivate users with a high degree of protection: the number of code combinations of radio key fobs is 4 billion ciphers.

Features of rim locks

Overhead systems are easy to install. They are locked from the outside with a key. A spinner is used from the inside, which allows them to do their job perfectly as a safety net.

Company offers:

• Mechanical combination lock with a latch and a bill of lading ZKP-2 is used on access doors, country gates or gates (left and right internal and external opening) with a thickness of 24-45 mm. Unlocking is done by simultaneously pressing several buttons (from 1 to 9). The code combination can be changed repeatedly.
• Model ZN4 030.0.1 with a latch meets the 4th security class according to GOST (out of 5 levers 3 are equipped with false grooves). Overhead mechanisms are mounted on wooden doors for internal opening. Products provide a given level of protectiondue to being located at a sufficient distance from the outer door covering.

Locking is ensured by four 18 mm steel bolts. They extend from the lock case by 4 cm. One bolt is equipped with a hardened steel rod that protects against sawing. The package includes 3 brass keys with a decorative cap for outdoor installation.

Integrated keyholes

When choosing mortise or overhead locks "Mettem", customer reviews make you inclined to buy this brand's product for steel and interior doors equipment. They do not violate the design performance of the entrance groups and reliably protect them. To determine the strength class (4 categories), the number of latches and the time required to open the lock are compared. The company "Mettem" specializes in the production of burglary-resistant systems with the highest, 4th category of reliability.

Level devices consist of code plates and massive internal elements. Their practicality is determined by the number of curly liners.

Model range of inset lever locks

• Do you intend to buy "Mettem" mortise lever locks? Consumer reviews perfectly characterize the ZV8 model. It is used for residential and public buildings. The design is locked for 4 four half-turns with four steel crossbars with a section of 15.5 mm. They protrude 4 cm from the case.
• Mortise lever devices ЗВ8 802.0.0correspond to the second safety class according to GOST 5089-2003. The design is locked in one direction. The remaining 3 crossbars are designed to securely fix the door. The front steel bar is included in the package. At the base - 6 levers that prevent opening.
• Mortise lock "Mettem" series ЗВ9 144.1.0 is equipped with a latch. The product meets the third safety class according to GOST (out of 5 levers 2 are equipped with false grooves) and is installed on the entrance groups made of metal and wood. The cross section of the crossbars, the deadbolt and the latches is 1.6 cm. The locking mechanisms protrude from the body by 4 cm and 2.4 cm. One of the crossbars is equipped with a high-strength metal rod that prevents sawing. Locking of a door is carried out on 4 full turns and an internal latch. The package includes 5 keys and 2 pads.

Cylinder (English) protection system

Door locks "Mettem" include in their design crossbar and cylinder (secret) part. The system works according to the principle of locking the cylinders in the body part with paired code and locking pins. They are distinguished by high secrecy and resistance to opening with master keys, but burglary-resistant properties are inferior to lever systems.

Especially popular are SG1 701.0.0. These are class 4 locks. The products are designed to protect the entrance groups of residential and public buildings. Unlocking is designed for 3 turns with four crossbars with a section of 1.6 cm, retractable from the body by 3.6 cm. One of them includes a steel sliding rod that protects against sawing. The body part is reinforced with bushings, which ensures the fastening of the armor plate. Removable outer strip facilitates inset mounting.

If the exclusive lock "Mettem" is to be chosen - the price of the device of the 4th security class satisfies the needs of economical users (about 1000 rubles). The manufacturing company surprised and delighted users with the new model ZV4 713.1.0. The design is designed to lock the door for 3 turns with three crossbars with a section of 1.6 cm, retractable from the body by 3.6 cm. One of them is equipped with a steel rod that prevents sawing. The body part is reinforced with bushings for attaching the armor plate. Vertical rods provide top and bottom locking. The design is equipped with a latch and reinforced fixation of the crossbar.

Advantages of "Mettem" locking mechanisms

The reliability of locking systems is achieved through unique developments:

• Placement of hardened rods in crossbars and a steel ball in the profile "square" of the lock, contributing to protection against key picking, sawing and drilling.
• The lock "Mettem" is equipped with traps that exclude the possibility of unauthorized opening.
• Weakened "tooth" design provides additional protection against burglary.
• The installation of steel armor plates on the cylinder mechanisms and the anti-corrosion coating of internal parts are aimed at increasing the rigidity of the product.

All "Mettem" locking systems are accompanied bycertificates and quality assurance (2 years of service). The design department of the company is constantly developing new models of locking devices and improving existing products.
