For Concrete Walls Order ACC 204 drill four 1/4"
(6 mm) dia. holes to a minimum depth of 2.5" (64
mm). Attach using concrete expansion anchors as
shown in 1, 2, and 3 (right).
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete
surface in the hole to be used for the concrete anchors. Do not drill into mortar joints! Be sure to mount in a solid part
of the block, generally 1" minimum from the side of the block. Cinder block must meet ASTM C-90 specifications. It is
suggested that a standard electric drill on slow setting is used to drill the hole instead of a hammer drill to avoid
breaking out the back of the hole when entering a void or cavity.
• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.

• 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. If
plaster/drywall is thicker than 5/8", custom fasteners
must be supplied by installer.
• Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the bolts, greatly reducing
their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).
