B252 Series Grade 2 Deadlatch
Ideal for use on gates, utility panels and pipe chases, B250 Series accepts conventional and FSIC cylinders and features a thumbturn “holdback.”
Overview
The B252 operates as a deadlatch for situations where the non-handled function of a deadbolt is desired but in a self-locking form. This makes it ideal for pool gates as a double cylinder and similar applications where relocking is essential to security. When used on solid doors as a single cylinder with thumbturn, the holdback function allows the latch to remain retracted so the lock can be used as a nightlatch
