TIP:
Use a thread-locking compound on the armature
screws to ensure a long lasting installation.

screw
8.
Tighten the armature screws enough so that
the armature plates can withstand a break-in
attempt, but loose enough so that the armature
plates can pivot slightly. Make sure the anti-
spin guide pins are in the two guide pin holes.

7.
Put a rubber washer between the two metal
washers and place them over the armature
screw between the armature plates and the
doors. This allows the plates to pivot around
the screw to compensate for door
misalignment.
9.
Screw the four short self-tapping screws through the mounting plate’s slotted holes, but do not over-
tighten them. Keeping them loose will allow for adjustment of the plate left or right so that the mounting
plate and the armature plates form a 90-degree angle. See the diagram below.
10.
Once the position of the mounting plate is
correct, use the eight long self-tapping
screws to permanently mount the
mounting plate.
11.
Drill the cable access holes. Run the power leads
through the cable access holes in the mounting plate
and through the holes in the door frame.
