Installation InfoDOOR & FRAME PREPARATION:
To assure lift-off capability,
the lower knuckles must be installed on frame, upper knuckles on the door.
For non-lift-off mounting, one upper knuckle
and one lower knuckle must be mounted to frame. One knuckle must be installed
AFTER door is hung. For non lift-off offset hinges only: Use one type “A” and
one type “B” hinge per door.
