Qty:1 New in Box. For doors that are 1 3/8″ to 1 3/4″ thick. Keyed double cylinder B252 (E0112) – cylinder x cylinder. The B250 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. 5/8″ throw deadlatch resists prying attacks and “shimming of the latch. Concealed frame reinforcer protects wood jamb against kick-in attacks. Free spinning, tapered cylinder collar with security insert resists wrenching and prying. Thumbturn “holdback” feature retains the deadlatch in a retracted position when desired. UL 437 listed option resists drilling and physical attack on the cylinder. 1″ housing diameter, 9/16″ throw Faceplate. 1-1/8″ x 2-1/4″ with square corners Strike. 1-1/8″ x 2-3/4″ with square corners (ANSI and round corner options available) Backset. 2-3/8″ (2-3/4″ option available) Door range. 1-1/2″-1-3/4″ conventional cylinders; 1-1/2″-2-1/8″ Full Size Interchangeable Core cylinders Trim ring. 1/8″ or 7/16″ wrought brass or bronze reinforced with security insert Cylinder. 6-pin solid brass, keyed 6-pin, S123 keyway, keyed different (KD) Keys.
