4920AN Heavy Duty Deadlatch (ANSI Size) provides flexible traffic control and easy installation. The flexibility of traffic control and installation is offered by 4920AN Heavy Duty Deadlatches.

This allows a "locked" entrance to be used as an exit by visitors already in the building. 1-3/4" [44.5 mm] minimum door thickness required. Interchangeable, without stile modification, with any MS1850SN Deadlock of the 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).
