Kaba Mas X-10: Protecting America’s Most Sensitive Information
When it comes to safeguarding our nation’s secrets, one lock has set the gold standard for over a decade: the Kaba Mas X-10. Trusted by the Department of War / Department of Defense, Central Intelligence Agency (CIA), National Security Agency (NSA), the Pentagon and even Air Force One, the X-10 is the U.S. Government’s only approved lock that meets Federal Specification FF-L-2740B, Style 1.
A Legacy of Security
The X-10 represents the latest evolution in a secure tradition, following the X-07, X-08, and X-09 series. Introduced in 2013, it incorporates lessons learned from earlier models while delivering new levels of reliability and user-friendliness.
Some of its most notable advancements include:
PowerStar™ Technology – a self-activating internal power plant, eliminating the need for external power or batteries
Backlit LCD Display – an improvement over the X-09, making operation easier in low-light conditions
DC Motor & Simplified Bolt Design – fewer parts mean improved durability and reduced maintenance
Modes of Operation
The X-10 can be configured to meet varying mission needs:
Single Combination Mode – one operator, one three-number code.
Dual Combination Mode – two operators, two unique combinations.
Supervisory/Subordinate Mode – a supervisory combination unlocks the lock, permitting subordinate use until relocked
Audit Features for Modern Security
The X-10 doesn’t just secure, it also tracks the number of successful openings, unsuccessful attempts, firmware level, and software date. This provides security officers with valuable data to identify tampering or misuse
Where You’ll Find It
From Pentagon offices to nuclear submarine launch systems, the X-10 is the silent guardian protecting America’s most sensitive national security information. Every GSA-approved container, vault door, and secure room that houses classified information is required to use this trusted technology.
