CONCRETE CEILING
• Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material. If mounting to concrete wall
covered with plaster/drywall is unavoidable, plaster/
drywall (up to 5/8" thick) must be counterbored as
shown below. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
WARNING

• Make sure that the supporting surface will safely
support the combined load of the equipment and all
attached hardware and components.
• Tighten concrete anchor bolt firmly, but do not over-
tighten. Overtightening can damage the bolt, greatly
reducing its holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
