Installation to a concrete or cinder block wall
Drill four 5/16" (8 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Insert anchors (G) in
holes fl ush with wall as shown. Attach wall plate
(K) using four #14 x 2 -1/2" wood screws (E) as
shown in Illustration A and 1, 2, and 3. Tighten all
fasteners.
Optional: Rotate wall arm 180° to position the arm
closer to the ceiling.
• Tighten wood screws fi rmly, 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
WARNING
• 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
specifi cations. 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.

• Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other fi nishing material. If mounting to concrete
wall covered with plaster/drywall is unavoidable (not
evaluated by UL), 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 (not evaluated by UL).
