SW-15

Housing

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.

"

Function

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 thumbturn on inside of door.

operation from outside is not affected. Clutching action
prevents damage to internal components.
