GRADE 1

4920AN Heavy Duty Deadlatch provides flexible traffic
control and easy installation for wood or hollow metal doors.

Function

For hollow metal or wood doors prepared for hardware according to the
specifications of the American National Standards Institute (ANSI), 4920AN
Heavy Duty Deadlatches provide precise traffic control. A key-controlled bolt
hold-back feature allows a door to free-swing part of the day and exit-only
when the bolt is free to latch. This allows a “locked” entrance to be used as an
exit by customers or visitors already in the building. Interchangeable, without
door modification, with any MS1850SN Deadlock of same faceplate shape
and backset. Replaces 4520 and 4720 ANSI Deadlatches. 1-3/4" minimum
door thickness required.

LATCHBOLT

trim ring information.
