The Kaba Mas X-10 High Security Lock is manufactured per General Services Administration (GSA) specification Section FL-L-2740B. Section 1.1.1 of this specification requires Limited Use for all approved locks.

Section 1.1.1 Limited Use “Locks tested and qualified under this specification are to be sold only to the Federal Government, Government contractors specifically authorized to purchase these locks, or other organizations specifically authorized or required by the Government to use these locks”.

Sales to Government personnel will require a Government credit card, a Government purchase order reference, or a Government identification or CAC card. Government contractors will require a CAGE Code. The X-10 Manufacturing serial number should be linked with the sales order information and stored in a secure database.

X-10 — Built to Withstand External Attacks
Approved by the GSA for use on approved Class 5 and Class 6 Filing Cabinets and Class 5 Vault Doors. The X-10 was developed in conjunction with the US Government and meets FF-L-2740 – Revision B (now includes two lock styles, Style 1, and Style 2). FF-L-2740B is the US Government’s highest security standard for container locks and doors. X-10 is only lock approved for “Style 1” applications.


Known for lock supremacy since their first X-O lock in 1992, Kaba Mas once again scores big with their latest vault door lock: The X-10. The Kaba Mas X-10 is THE go-to lock for securing U.S Government safes, containers, vaults, and cabinets. Currently, close to one million X-O locks are installed in high-security places, including:

  • The Pentagon
  • DoD
  • CIA
  • NSA
  • Bases
  • Military Vessels
  • Air Force One

Building upon the success of its predecessor, the Kaba Mas X-10 features a new sealed lock case, lock bolt design, and beefed-up motor. The result is better performance and enhanced protection. Plus, installation is easy—the lock mounts through the case, eliminating the need to install the back cover first.

This vault door lock also racks up eco-points with self-powered green technology. This means no batteries to change and no scheduled maintenance.  This makes it the most environmentally-advanced lock, reducing service costs while providing consistent, ‘round the clock prevention against threats. It’s why the X-10 is the only electro-mechanical lock approved for “Style 1” applications, as set forth by FF-L-2740B—the Government’s highest security standard for storage container locks and doors.

Please note: The characteristics and operating features of a Style 1 and Style 2 lock are not the same. The Kaba Mas X-10 is the only self-contained lock and represents the best overall value. The X-10 is the lock awarded the distinction of being approved for Style 1 applications.
