5 Obtain the seismic anchor bolts, and the floor mounting hardware kit.
6 Drill a 0.7 in. (18 mm) diameter anchor hole 4 in. (10 cm) deep at each of the four anchor
positions. If the longer concrete anchor (M12/50) is being used, a deeper anchor hole (up to
1 in. or 2.5 cm deeper) may be required.
7 Go to step 10.
8 Obtain the floor mounting hardware kit and the anchor setting tool.
9 Drill a 0.6 in. (16 mm) diameter anchor hole 2 in. (5 cm) deep at each of the anchor positions.
10 Completely remove debris from the anchor hole and surrounding area with the shop vacuum
(or approved hazardous waste removal method). Inspect the anchor hole for any concrete
chips. The anchor holes must be completely clear to properly seat the anchor.
11 Cover the anchor holes using plugs if the rack will not be installed immediately.
12 STOP. This procedure is complete.
Note — Use the exact drill size for drilling anchor holes to achieve
maximum anchor strength.
