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 began producing locking mechanisms in the city of 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. The internal elements are zinc plated or made of 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 reliable protection against picking master keys.
Types of Locking Devices
The plant is famous for the production of mortise and overhead level locks with protective traps from opening. The product range is different with models with a different number of levers - from 4 to 10. Separately, the Mettem lever-code locks are positioned, including the ability to lock systems. Installation of castle structures is successfully done in the doors of wood and metal.
Combined devices are characterized by the presence of two different protections - level and cylinder.
The cylinder type of protection 2-4 safety classes according to GOST is certified for installation in armored and fire doors.
Drive locks
Access installations of multi-storey buildings, industrial and office buildings are blocked by a common use system or a separate unlocking device assigned to each owner.
Locks "Mettem" are equipped with a limited number of keys. However, the increased risk of their loss has affected 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 24-35 mm thick, and the second - 40–45 mm.
All movable elements of a mechanical encoding device are made of high strength steel. The mechanism for dialing a code includes 10 buttons. The cipher can be changed. Partial disassembly will require time, which is disadvantageous for the cracker. Code combinations have from 1 to 4 thousand ciphers. Secret latches are often used to lock the country gates.
Radio-controlled safety devices
An overhead or mortise mechanical combination lock is supplemented by an electronic control system; keys are not required for its use. Management is carried out by a charm. The backup power source is a 2.2 A / h battery. The battery is designed for uninterrupted operation of the mechanism for 6 days. Electronic and mechanical devices conquer users with a high degree of protection: the number of code combinations of remote controls is 4 billion ciphers.
Characteristics of overhead locks
Overhead systems are easy to install. They are locked on the outside with a key. A spinner is used from the inside, which allows them to perfectly cope with their task as a safety net.
Company offers:
- A mechanical combination lock with a latch and a consignment note 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 performed by pressing several buttons simultaneously (from 1 to 9). Code combination may change repeatedly.
- The model ZN4 030.0.1 with a latch corresponds to safety class 4 in accordance with GOST (3 out of 5 levers are equipped with false grooves). Installation of overhead mechanisms is carried out on wooden doors for internal opening. Products provide a specified level of protection due to the location at a sufficient distance from the outer door cover.
Locking is provided by four steel crossbars with a section of 18 mm. They extend from the lock case by 4 cm. One bolt is equipped with a hardened steel rod that protects from cutting. The package includes 3 brass keys with a decorative pad for outdoor installation.
Mortise leveling keyholes
Choosing Mettem mortise or patch locks, customer reviews allow you to lean toward buying products of this brand for the equipment of steel and interior doors. They do not violate the design 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 burglar-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 figured inserts.
Lineup of pad locks
- Do you intend to buy Mettem mortise locks? Customer reviews perfectly characterize the model ZV8. It is used for residential and public buildings. The design is locked for 4 four half-turns with four steel crossbars with a cross-section of 15.5 mm. They exit the casing by 4 cm.
- Mortise leveling devices 8 802.0.0 correspond 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 lock the door. The package includes a front steel strip. At the base - 6 suvald, preventing opening.
- Mortise lock "Mettem" of the ZV9 144.1.0 series is equipped with a latch. The product meets the third safety class according to GOST (2 out of 5 levers are equipped with false grooves) and is installed on the entrance groups of metal and wood. The cross-section of the crossbars, deadbolts and latches is 1.6 cm. The locking mechanisms extend 4 and 2.4 cm from the body. One of the crossbars is equipped with a high-strength metal rod that prevents cutting. The doors are locked for 4 full turns and an internal bolt. The package includes 5 keys and 2 pads.
Cylinder (English) protection system
Door locks "Mettem" include in their construction crossbar and cylinder (secret) part. The system operates on the principle of locking the cylinders in the housing with pair of code and locking pins. They are distinguished by high secrecy and resistance to tampering with master keys, but tamper-resistant properties are inferior to level systems.
ZV1 701.0.0 is especially popular. These are security 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 cross section of 1.6 cm, extendable from the body by 3.6 cm. One of them includes a steel sliding rod that protects from cutting. The hull is reinforced with bushings, which ensures the fastening of the armor plate. Removable outer strip facilitates insert mounting.
If the exclusive Mettem lock is subject to selection, the price of a security class 4 device meets the needs of frugal users (about 1000 rubles). The manufacturing company surprised and pleased users with the new model 4 713.1.0. The design is designed to lock the door 3 turns with three crossbars with a cross section of 1.6 cm, extendable from the housing by 3.6 cm. One of them is equipped with a steel core that prevents cutting. The hull is reinforced with bushings for mounting the armor plate. Vertical rods provide upper and lower 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:
- Placing hardened rods in the crossbars and a steel ball in the profile “square” of the lock, which contribute to protection against key selection, saw cut and drilling.
- The lock "Mettem" level is equipped with traps that preclude the possibility of unauthorized opening.
- The relaxed “tooth” of the construction provides additional protection against hacking.
- The installation of steel armor plates on cylinder mechanisms and anti-corrosion coating of internal parts are aimed at enhancing the rigidity of the product.
All Mettem castle systems are accompanied by certificates and a quality guarantee (2 years of service). The design department of the company is steadily developing new models of locking devices and will improve existing products.
