Product Overview

The 4550 MS Deadlock Lever easily unlocks an MS Deadlock with approximately three pounds of downward force. The spring-loaded lever relocks with an upward motion. Indicator signals lock status. Can be installed in place of existing key cylinder or cylinder type thumbturn on inside of door. Key operation from outside is not affected. Clutching action prevents damage to internal components. Ordered for left or right hand door, but is easily reconfigured in the field to accommodate either door swing. '"Locked" in red letters or "Open" in green letters appear on white background when bolt is thrown or retracted respectively.
