For Concrete Walls
use wall arm (
A
), making sure that
it is level, as a template to mark holes. Drill 1/4" (6 mm)
dia. holes to a minimum depth of 2.5" (64 mm). Concrete
must be 2000 psi density minimum. Insert anchors in
holes flush with wall as shown (right). Place wall arm
over anchors and secure with #14 x 2.5" (6 mm x 65
mm) wood screws. Tighten all fasteners.

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 specifica-
tions. 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 hard-
ware and components.
• Tighten concrete anchor bolts 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.).
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 below. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
