Combination Locks

Whilst vault and safe locks have been around since the middle of the nineteenth century, the modern manipulation proof combination lock was developed by Sargent and Greenleaf for government use in the late 1940’s. For the next 50 years the design of combination locks was improved to make the locks more robust and even more secure and resistant to manipulation by would be thieves. By the late 1980’s the modern manual combination lock was at its peak. Electronic locks entered the high security market and now compete with manual combination locks.

Sargent and Greenleaf Combination Lock

We believe that in today’s modern world there is still a place for the manual combination lock. It is a little like digital versus analogue watches there is something inherently beautiful about a well-crafted mechanism that does one job well. That is why we continue to offer our smaller safes with the option of a manual combination dial.

Lexam 1548

Some people might think that it is strange that we have chosen a Chinese made manual combination lock for our range of safes. However, we believe that the Lexam 1548 represents a great balance between quality and cost. Many thousands of this lock have been produced over many years and it has proven to be robust and trouble free. This is because of its history and heritage, which few people know.
