The code rotary lock is equipped with a mechanical protection system. The device is designed with security and reliability in mind for storing items. It is suitable for installation on wooden and metal doors. Convenient for storing valuables in a safe, locker room, clothing locker, backpack, or case. It is used for the security of garages, workshops, gates, and other utility objects. The lock is equipped with a code consisting of four digits. It allows for the selection of a password from a range of up to 10,000 options. Such a number of combinations reduces the likelihood of theft. For security purposes, it is recommended to change the standard password immediately upon installation of the lock.

Functionality and Characteristics

The device has the appearance of a rotary handle with four drums for entering the code. The design of the mechanical lock consists of a locking mechanism and a panel. At the bottom, there is a slot for opening/closing with a master key. It is used for emergency door opening. Locks can be opened with a master key if necessary, but it does not come with the lock. The material of the product allows for the lock to be installed on the outside. The product is resistant to temperature fluctuations, high humidity, and water. The lock is easy to program and use.

Advantages of the Product:

• reliability;
• practicality;
• versatility;
• functionality;
• low maintenance requirements.

Unlike button locks, the rotary rollers of the lock do not allow an intruder to identify frequently used digits, as fingerprints do not appear on the rollers during use. The lock does not require electrical power. When opening the doors, the user sequentially enters the set password by rotating the rollers. The door opens after the bolt is released. A spring mechanism returns the locking tongue to its original position and closes the door. You can place an order for the rotary code lock on the UHL-MASH website.
