Figure 4-12 Drilling a hole and installing an expansion bolt
Avoid drilling holes in the utility pipes and/or cables attached to back of the wall.
● To prevent dust inhalation or contact with eyes, wear safety goggles and an
anti-dust respirator when drilling holes.
● Clean up any dust in and around the holes using a vacuum cleaner and
measure the distance between holes. If the holes are inaccurately positioned,
drill a new set of holes.
● Level the head of the expansion sleeve with the concrete wall after removing
the bolt, spring washer, and
at washer. Otherwise, the mounting bracket will
not be securely installed on the concrete wall.
Step 3 Align the mounting bracket holes with the drilled holes, insert expansion bolts into
the holes through the mounting bracket, and then tighten the expansion bolts.
