Description
The Adams Rite 4550L-02-130 is an interior deadlock lever that replaces key cylinders or thumbturns on MS pivoted bolt deadlocks. Operating with approximately 3 lbs. downward force, it provides intuitive unlock control while a spring-loaded design returns the lever to horizontal and relocks with upward motion. An indicator signals lock status, making it ideal for schools, offices, and facilities requiring quick manual access without external key operation.
This lever fits most MS deadlock models including MS1850S, MS1950, and MS1837, plus derivative flushbolts like the 1870 and 1877. Not compatible with 7/8 in. backset locks or MS1890/2190 deadlocks. Installation replaces the existing cylinder; clutching action protects internal components. As an authorized Adams Rite dealer, E.D. Locks provides expert guidance and complete support.
