Adams Rite 4550L-01-121 4″ Deadlock Lever Trim with Duronotic Clutch

The 4550L-01-121 MS Deadlock Lever works with the MS Deadlock with approximately three pounds of downward force on a 3″ lever whereas the spring-loaded lever relocks the device with an upward motion. The indicator is self-driven by lock bolt itself which indicates lock status. It can be installed in place of existing key cylinder or cylinder type thumb-turn on inside of door. Its clutching action prevents damage to internal components. The 4550 Deadlock Lever is not found compatible with 7/8″ backset locks.
