The mechanical combination lock is one of the most reliable solutions for securing safes and fire-resistant cabinets. Entering and changing the code takes slightly more time than with an electronic lock, but this is offset by unmatched mechanical reliability. Since no key is required, there is no risk of key loss or duplication. The safe is opened with a unique numerical combination, ensuring a high level of protection.
Mechanical combination locks are tested and certified to EN 1300 (Class A, B or C), the European standard for high-security safe locks. The combination is adjustable and consists of 3 or 4 double digits (6 or 8 digits), providing between 1,000,000 and 100,000,000 theoretical possibilities.
From Class B onwards, these locks are equipped with manipulation protection. They also include an integrated blocking mechanism that prevents operation if the spindle or dial is forced. Different dial types are available, including the “spy proof” dial, which prevents unauthorized observation of the code. Mechanical combination locks can be installed on virtually all safes and fire-resistant cabinets.
