Product Description

Mechanical combination safe lock with key 

YOSEC Combination safe locks are still used in select applications on modern safes. The reliable, consistent operation, even in tougher environmental conditions make them suitable for situations where electronic locks may not be, yet keyless operation is still required.

Mechanical combination locks, or dial combination locks, are a time tested and reliable form of keyless security on safes, providing only a reputable and reliable brand and model is used.

Good quality combination locks will have parts engineered to ensure accuracy and in turn security, by making it difficult to manipulate the lock to open. Combination dial safe locks are available in 3 wheel or 4 wheel configurations. The number of wheels directly relates to the amount of numbers in the code used to unlock the safe. A 3 wheel, or 3 number combination lock will have 1 million possible number combinations, with 800,000 useable combinations. A 4 wheel combination lock will have 100 million possible number combinations with 80 million useable combinations.

Sargent and Greenleaf (S&G) and LaGard are the 2 most prominent brands of mechanical combination safe locks, both of whom have been producing safe locks for decades.

Safe Central also use the more recent 'Big Red Series' combination safe locks which are very well made and offer the same features and functions as the LaGard and S&G equivalents.
