The FALCON B581BDAN626 is a B Series small format storeroom lever lock configured with the Dane lever trim, a 57435 latch, and a 5164 strike plate in a Satin Chrome finish. Designed for commercial and institutional door hardware applications, this mortise-style cylindrical lock provides storeroom function, meaning the exterior lever is always locked and requires a key for entry while the interior lever remains free for egress. The interchangeable core design allows the lock cylinder to be removed and replaced without a locksmith, reducing re-keying labor significantly. At 3.7 pounds, it is a solid, hardware-grade unit suited for high-traffic door openings.
This lock is intended for storeroom, storage, and utility room applications in commercial, institutional, and light industrial buildings. The storeroom function makes it appropriate for doors where controlled access from the outside is required at all times while maintaining free egress from the inside. The Satin Chrome finish suits standard commercial interior door hardware schedules. The included 57435 latch and 5164 strike are matched components, reducing the need to source hardware separately. Installation is handled by qualified locksmiths or commercial door hardware technicians.
Designed as an OEM-style cylindrical lock replacement for commercial and institutional doors requiring storeroom function with small format interchangeable core hardware.
Installation should be performed by a licensed locksmith or qualified commercial door hardware technician. Verify door prep dimensions and backset before installation to confirm compatibility with the existing door bore. Ensure the door is in a closed, secure position and the building access plan is updated after any core change. Consult applicable building codes and ANSI hardware standards for proper function and fire-rated door compliance where required.
