MS®+1890 Latch/Deadlock
Provides both Maximum Security after hours and convenient traffic control management during the day. Three modes of door control are offered:

1. Both lock and latch bolts retracted for unrestricted entry and exit during business hours.

2. Handle-operated latch for exit-only traffic.

3. Maximum Security hookbolt for overnight locking.

Handles should be specified for one side only or both sides - with handles on both sides the problem of a door that stands ajar because of wind and air-conditioning pressures is solved with minimum traffic impediment. Latchbolt reversible; supplied non-handed unless specified.
NOTE: Not suitable for use with Electric Strikes - handle operation does not retract deadbolt.
