Adams Rite MS+1891W - Series MS® Deadlock w/ Latchbolt - Radius Faceplate with Weatherstrip
MS+1891W Series MS Deadlock with Latchbolt Radius Faceplate with Weatherstrip provides a maximum security deadlock for after hour and traffic control with deadlatch convenience during business hours.
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:
1. Both lock and latchbolts retracted for unrestricted entry and exit during business hours
2. Handle-operated latch for exit-only traffic just after closing
3. Maximum security MS hookbolt for overnight lockup. When using trim (available separately) to activate, handle or paddle operates latchbolt only.
360° turn of key or thumbturn projects or retracts the hookbolt. 120° further turn retracts latchbolt as well. MS1891W Deadlock w/ Latchbolt 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, or thumbturn such as the 4066 Thumbturn, available separately. The MS1891W Deadlock w/ Latchbolt accepts cylinder from either or both sides. When using trim (available separately) to activate, handle retracts springloaded latchbolt only.
