DoD Lock Program Training



Training classes for locks that meet federal specification FF-L-2740B are limited to the Federal Government employees, and US Government contractors specifically authorized to use these locks, or other organizations or persons specifically authorized or required by the US Government to use these locks.

The DoD Lock Program offers group training on combination locks that meet Federal Specification FF-L-2740B.  This includes the Kaba Mas Model X-10 and the Sargent and Greenleaf Model 2740B.  If you have a large group of students and want training at your facility, please email our training coordinator to request schedule availability.

Information about various combination locks may be found on our website under the "Security Locks" section on our Instructional Documents and Forms web page.  Or you can click on the training page in the tabs above or in the menu to the left for the lock of your application to review instructional documentation.
