Adams Rite Exit Lever for Dead Bolt Locks with indicator
Handed: Yes - Left & Right hand doors - Field Reversible
Used on inswing or outswing doors with 31/32 or 1-1/8 backsets
Color: Dark Bronze or Aluminum
Easy unlocking of any MS deadbolt by approximately 3 lbs. downward force on a 3" lever. Lever is spring loaded to horizontal, relocks with upward motion. Indicator signals lock status. Can be installed in place of existing key cylinder or cylinder type thumb-turn on inside of door.
Housing:
Aluminum casting is 1-3/8 wide x 7-1/2 long x 1 deep.
Attached to door stile by four #10 screws.
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.
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.
Compatible Deadbolts:
Any MS pivoted bolt deadbolt including "Schoolhouse" versions can be fitted with the 4550: 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 latchlock or with 7/8 backset locks.
Operation:
Turn lever downward 90o to unlock. When released, lever returns to horizontal. Turn lever upward 90 degrees to re-lock. Key operation from outside is not affected. Clutching action prevents damage to internal components.
Handing:
Can be ordered for left or right hand door, but is field reversible in the field.
