MS+1890 SeriesMS® Deadlock/Deadlatch

MS+1890 Series MS Deadlock/Deadlatch provides a maximum security deadlock for after hour and traffic control with deadlatch convenience during business hours.

Function:

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 any standard 1" [25.4 mm] length, 1-5/32" [29.4 mm] diameter mortise cylinder with MS® cam such as the 4036 Mortise Cylinder, available separately or thumbturn such as the 4066 Thumbturn, available separately. Lock accepts cylinder from either or both sides. When using trim (available separately) to activate, handle retracts spring-loaded latchbolt only. For door thickness other than 1-3/4”, please contact factory.
