7. Put a rubber washer between the two
metal washers and place them over the
armature screw between the armature
plate and the armature plate holder. This
allows the plate to pivot around the screw
to compensate for door misalignment.
9. Screw the two 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 so that the long
edge of the mounting plate and the armature plate are parallel. See the diagram below.

10. Once the mounting plate position is correct,
use the four long self-tapping screws to
permanently mount the mounting plate.

The rubber washer is sandwiched
between the two metal washers
and all three are placed between
the armature plate and the
armature plate holder.

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

11. Drill the cable access hole. Run the wiring
through the cable access hole in the
mounting plate and through the hole in the
door frame.
