Product at A Glance

  • This lever is not compatible with 7/8” backset locks or MS+1890 latch-lock.
  • The word “LOCKED” will appear in red letters on a white background on the indicator below the lever when the lock bolt is thrown, and the word “OPEN” will appear in black letters on a white background when the latchbolt is retracted.
  • The indicator is driven by the lock bolt itself
  • Turning the lever downward 90 degrees will unlock it. When it is release the lever will return to its horizontal position. To relock, turn the lever upwards 90 degrees.
  • Key operation from outside is not affected by inside operation
  • Clutching action prevents damage to internal components.
  • Stop clearance - The lever housing projects 11/16" forward of the cylinder backset centerline. Depending on the height of the door stop and the width of the door or the jamb gap, it may be necessary to modify the stop to clear the housing, for fin type stops (can be done easily). Hollow stops may not allow the use of lever.
  • Aluminum lever with end-return design offers comfortable grip to lock or unlock
