7 Tip the cabinet again and place an isolator pad over each set of anchor
holes. Ensure that each isolator pad mirrors the placement of each
bracket.
8 Remove the nut, the flat washer, and the load indicating washer from the
top of an anchor. Then, tap the anchor into a hole.
9 Place an isolation bushing and a plate washer over that anchor. Screw the
flat washer and the load indicating washer onto the threaded rod of the
anchor. Then, thread the nut back onto the anchor.
10 To tighten the anchor, insert a slot-head screwdriver in the top of the
threaded rod and use an open-ended wrench to tighten the nut.
The slot-head screwdriver prevents the threaded rod from turning. As the
anchor tightens, you will no longer need to use the slot-head screwdriver
to hold the threaded rod. You must then fully tighten the anchor.
11 Torque the anchor to 50 ft-lb. using a socket wrench.
12 Repeat step 8 to step 11 for each anchor.
