6.Depending on the type of door being protected, drill holes according to the diagrams below:

opposite side of the door.

1/2” (12 .7mm) 5/16” (8mm)

Drill an 5/16” (8mm) dia. hole on the door for the armature screw, and drill a 1/2” (12.7mm) dia. and 1” (25mm) deep hole for the sexnut screw.

7.Put a rubber washer between the two metal washers, and place them over the armature screw between the armature plate and the door. This allows the plate to pivot around the screw to compensate for door misalignment.

The rubber washer will be sandwiched between the two metal washers.

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.

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

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 left or right so that the mounting plate and the armature plate form a 90-degree angle. See the diagram below.
