MS+® 1890 Series MS® Deadlock/Deadlatch
Maximum security MS+ deadlock after hours, plus the convenience of traffic control management during the business day. Typical installation is a bank or store requiring three modes of door control:
- Both lock and latchbolts retracted for unrestricted entry and exit during business hours
- Handle-operated latch for exit-only traffic just after closing
- Maximum security MS hookbolt for overnight lockup. When using trim (available separately) to activate, handle or paddle operates latchbolt only.
OPERATION
360° turn of key or thumbturn projects or retracts the hookbolt. 120° further turn retracts latchbolt as well. Lock accepts cylinder from either or both sides. When using trim (available separately) to activate, handle retracts spring-loaded latchbolt only
