Mechanical Combination Locks

For Protection of Arms, Ammunition, and Explosives (AA&E)

All new GSA approved weapons containers, GSA approved armory vault doors, and GSA approved field safes are required to have a mechanical combination lock meeting Federal Specification FF-L-2937, Combination Locks, Mechanical and its Amendment 2

Existing weapons containers, vault doors, and field safes may continue to use a mechanical combination lock meeting the requirements of Underwriters Laboratories Inc. (UL) Standard 768, Group 1.  If the existing UL 768, Group 1 lock fails, or requires replacement, it must be replaced with a lock meeting FF-L-2937.  These security containers and armory vault doors should not have an FF-L-2740 electromechanical combination lock.

FF-L-2937 mechanical combination locks meet performance and design requirements of UL Standard 768, Group 1 publication.  These locks resist manual manipulation for a period of 20 man hours.  FF-L-2937 locks are available from DLA Land and Maritime.  Click on the Ordering Information tab for information on how to procure mechanical combination locks.
