    BEST Access Systems: The Gold Standard in SFIC and Institutional Security

    If you manage a hospital, a university, or a government facility, you know that BEST Access Systems is the benchmark for high-traffic durability. In 1921, Frank Best invented the Small Format Interchangeable Core (SFIC), a revolutionary design that allows a lock to be rekeyed in seconds without removing the hardware from the door. Today, BEST continues to lead the industry with locks that are engineered to outlast the building they are installed in.

    At Lock Depot, we stock the legendary 9K Series Cylindrical Locks—which have famously exceeded 100 million test cycles—and the 45H/40H Series Mortise Locks. Whether you need a 7-pin "Standard" core or the patented high-security CORMAX system, BEST provides the ultimate balance of physical strength and key management efficiency. We specialize in providing the "Less Core" hardware you need to match your existing facility master key system.

    PRO TIP: The 100 Million Cycle Difference

    Many "Grade 1" locks are tested to 1 million cycles. The BEST 9K has been independently tested to over 100 million cycles. If you have a door that is constantly failing or sagging, stop replacing it with standard hardware. Upgrading to a 9K with its hardened steel through-bolt studs and cast-construction hubs is the only way to permanently solve high-traffic maintenance headaches.

    BEST Access hardware ships from our warehouses across America. Stocking dealer with SFIC expertise, custom keying, and master key support available.

    BEST Access Systems FAQ

    What is an SFIC (Small Format Interchangeable Core)?

    SFIC is a lock core design invented by BEST that allows the entire core to be swapped out in seconds using a special control key. This means a facility can rekey a door instantly without removing the lock from the door or calling a locksmith.

    Why is the BEST 9K considered the most durable lever lock?

    The BEST 9K has been independently tested to over 100 million cycles, compared to the 1 million cycle minimum for Grade 1 certification. Its cast-construction hub and hardened steel through-bolt studs make it virtually indestructible in high-traffic environments like schools and hospitals.

    Can I order BEST hardware without a core installed?

    Yes. BEST hardware is commonly ordered "Less Core" (LC), which means the lock arrives without a core installed. This allows your facility's locksmith to install a core that is already cut to match your existing master key system.
