Specifications:

  • Housing: Aluminum casting is 1-3/8” wide x 7-1/2” long x 1” deep.
  • Lever: 3” long aluminum with end-return design offers comfortable grip to lock or unlock.
  • Indicator: Words “LOCKED” in red letters or “OPEN” in black letters appear on white background when lock is thrown or retracted. Indicator is driven by lock bolt itself.
  • Stop Clearance: Lever housing projects 11/16” 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.
  • Compatible Deadlocks: Any MS® pivoted bolt deadlock including “Schoolhouse” versions can be fitted with the 4550 including MS1850S, MS1950, MS1837, etc. Derivative units such as 1870, 1870HM, or 1877 flushbolts (bolt into threshold) are also operable by the 4550 lever. Not compatible with MS+1890 Deadlock/Latch or with 7/8” backset locks.
  • Options: Available in three finishes to match anodized aluminum finishes. Can be ordered for left or right hand door, but is easily reconfigured in the field to accommodate either door swing.
