For traditional BEST Interchangeable core applications, the 150 series offers the security and convenience of a patented solution that will operate a wide variety of locking hardware, including cylindrical locks, padlocks, deadbolts, and cabinet locks. The 150 series is available in 6 or 7 pin sizes, and utilizes the same service equipment as standard BEST cores. Because the patented pins are factory installed, the Peaks® cores use the same combinating procedures as the standard BEST cores.
