Schlage B250PD Nightlatch Deadbolt

The B250-Series nightlatch features a 9/16" (14 mm) deadlatch that prevents "shimming" the bolt with a credit card or similar tool. A "hold-back" feature retains the deadlatch in a retracted position when desired. Trim rings are reinforced with hardened steel inserts. Brass or bronze faceplates are self-adjusting for beveled door edges.
