Installation to a concrete or cinder block wall
Drill four 1/4" (6 mm) dia. holes to a minimum depth of
2.5" (64 mm). Attach wall plate (A) using four concrete
anchors
(C)
and four #14 x 2 -1/2" wood screws (B) as
shown in Illustration A and 1, 2, and 3. Tighten all
fasteners.

• Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the screws, greatly
reducing their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
WARNING
• 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 right. If plaster/drywall is
thicker than 5/8", custom fasteners must be supplied
by installer.
WARNING
WARNING
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual con-
crete 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 wall will safely support four times the combined load of the equipment and all attached
hardware and components.
