Kaba Mas of Lexington, Kentucky, has added the newly designed X-10 to its X-0 series of high-security locks. The X-10 meets the revised specification FF-L-2740 (Revision B), the U.S. government’s highest standard for container locks and doors. It is approved by the U.S. General Services Administration for use on Class 5 and Class 6 filing cabinets and Class 5 security vault doors. The lock is self-powered using PowerStar technology. Rotating the dial powers up the lock and enters the combination. Intuitive visual controls guide the operator through programming and audit features. The lock features automatic lock reset and high-security combination scramble, and it resists external manipulation and environmental attack.
