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.

Features

  • Housing: Aluminum casting is 1-3/8" wide × 7-1/2" long × 1" deep [34.9 mm × 190.5 mm × 25.4 mm].
  • Lever: 3" [76.2 mm] long aluminum with end-return design offers comfortable grip to lock or unlock.
  • Indicator: Words "LOCKED" in red letters or "OPEN" in green letters appear on white background when bolt is thrown or retracted respectively. Indicator is driven by lock bolt itself.
  • Stop Clearance: Lever housing projects 11/16" [17.5 mm] forward of cylinder backset centerline. Depending on height of door stop and width of door/jamb gap, it may be necessary to modify the stop to clear the housing. For fin type stops, this is easily accomplished. Hollow stops may preclude use of lever. Please contact factory for more detailed information.
  • Compatible Locking Devices: Any MS pivoted bolt deadlock including Schoolhouse versions can be fitted with the 4550 including MS1850S, MS1950. Derivative units such as 1870 or 1870HM, flushbolts that bolt into threshold are also operable by the 4550 lever. Not compatible with MS+1890 Deadlock/Deadlatch or 2190 Interconnected Deadlock/Deadlatch or with 7/8" [22.2 mm] backset locks.
  • Standard Package: Individually boxed with mounting hardware and drive pins for both single point and threshold bolt-equipped locks.
