Required tools: drill, wrench, 7/16" (11.0mm) bit, for wood anchoring: 9/32" (7.20mm) bit, for masonry anchoring: 3/8" (9.5mm) masonry drill bit.

The steps are as follows:

1. Tip the safe on its right side. (door hinges horizontal with the floor)
2. Unlock the safe and open the door.
3. Look on the bottom (outside) of the safe for two indentations in opposite corners. Using a 7/16"(11.0mm) bit, drill a hole through each indentation perpendicular to the bottom of the safe.
4. Close the door and tip the safe upright. Place it where desired and re-open the door.
5. Use a screw or drill bit to mark the floor through both holes.
6. Move the safe aside to clear both marked spots for drilling.
7. Drill into the floor: For wood using a 9/32" (7.2mm) bit, drill a hole 2 1/2" (64mm) deep in each marked spot.  For masonry: using a 3/8" (9.50 mm) bit, drill a hole 2 1/2" (64mm) deep in each markedspot. Install a masonry anchor in each hole.
8. Replace the safe in the desired position, with the holes in the safe aligned with those in the floor.
9. Securing the safe: For wood: pass each lag screw through a washer, then through the safe and into a hole.  Tighten with a wrench.  For masonry: pass each lag screw through a washer, then through the safe and into a masonry anchor. Tighten with a wrench.
