To hold bolt retracted, push it in and secure by reverse turn of key. Interchangeable, without stile modification, with any MS1850SN deadbolt of same backset and faceplate shape. Replaces 4520 and discontinued 4720 ANSI Deadlatches. For hollow metal or wood doors prepared for hardware according to the specifications of the American National Standards Institute (ANSI).
