Installation (Summary)

1. Align the Lock Guard on the door frame so the second screw hole from the bottom sits level with the key entry point.

2. Mark all 4 holes with a pencil and remove the guard.

3. Drill pilot holes (use 3 mm or 7/64” bit) to the depth of the screw.

4. Place the guard back over the holes and secure with the 4 screws supplied.

5. Do not over-tighten. Ensure a firm fit against the frame.

Note: Fits most security doors. Use a Phillips head screwdriver and drill for installation.
