Features:

• 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.
