Kaba Mas X-10 High Security Combination Lock

The X-10 is Impervious to External Attack
dormakaba is proud to distribute the X-10 High Security Combination Lock, a product designed and developed by Kaba Mas in Lexington, Kentucky. With nearly a million sold, Kaba Mas has been the primary supplier of High Security combination locks to the U.S. Government for over 25 years.
The X-10 was developed as a result of the latest revision to Federal Specification FF-L-2740 (now revision “B”). This revision, which is the U.S. Government’s highest security standard for combination locks used to protect Classified and National Security Information, now specifies two styles. Style 1 requires the lock to be self-powered. The X-10 is the only Style 1 combination lock and is approved for use on all GSA Approved Security Containers and Vault Doors. The X-10 is also approved for use on Federal
Specification FF-L-2890B locks installed on pedestrian doors to Secure Rooms and Sensitive Compartmented Information Facilities (SCIFs).
The X-10 is self-powered, using green “PowerStar” Technology. Simply rotate the dial to power up the lock and enter the combination. Intuitive, visual controls guide the operator through programming and audit features. The X-10 provides all the benefits of high-security electromechanical locking system, independent of batteries or outside power sources.
New – Backlit Display
A unique, standard feature of X-10 combination locks manufactured after March 25th, 2014 is the backlit LCD. With a simple turn of the dial, the screen illuminates, eliminating the need for external light sources when locks are installed in poorly lit areas. The backlit display was approved by the General Services Administration (GSA).
The X-10 can be programmed for three separate modes of operation and features Automatic Lock Reset. The X-10 resists all forms of external manipulation and environmental attack, as required by Federal Specification FF-L-2740B.

The X-10 can be ordered directly from the Government through either the Defense Logistics Agency (DLA) or from the General Services Administration (GSA). Each agency has its own NSN – as follows:
