ADAMS RITE MS1890 Mortice Hooklatch Case

The Adams Rite MS1890 Mortice Hooklatch Case is designed to provide maximum security for commercial premises after hours, combined with convenient traffic control during the business day. This dual-function lock is ideal for narrow stile metal doors, allowing you to manage access seamlessly.

Operating via a screw-in cylinder (available separately), a 360° turn of the key throws or retracts the heavy-duty hookbolt. When the lock is unlocked, a further 120° turn retracts the latchbolt, allowing for easy daytime traffic. Additionally, a latch holdback snib is located inside the bolt cavity, which can only be accessed when the hookbolt is thrown, allowing the door to be set to free-swinging when required.

Please note that all faceplates and strike plates must be purchased separately. This product is available in multiple backsets, case depths, and weights; please select your required options from the options below.
