Flexibility of traffic control and installation is offered by 4900 Heavy Duty Deadlatches. A key-controlled bolt hold-back feature allows for two-way traffic for applications which require free entrance at certain times and exit-only at other times. 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 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).
