Installation to Solid Concrete and Cinder Block Wall
1
Position wall plate (
AA
) on wall so that upper slots
are
2.1" above desired center of screen.
Use wall
plate (
AA
), making sure that it is level, as a template
to mark holes. Drill four 5/16" (8 mm) dia. holes to a
minimum depth of 2-1/2" (64 mm). Concrete must be
2000 psi density minimum. Insert anchors (
DD
) in
holes flush with wall as shown in figure 1.4. Place
wall plate (
AA
) over anchors and secure with
#14 x 2-1/2" (6 mm x 64 mm) wood screws (
CC
) as
shown in figure 1.5. Make sure wall plate is level and
tighten all fasteners.
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete
thickness 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.

• 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.).
• Concrete anchors are
not
intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material as shown right. If mounting
to concrete wall covered with plaster/drywall is un-
avoidable, plaster/drywall (up to 5/8" thick) must be
counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tighten-
ing screws. If plaster/drywall is thicker than
5/8", custom fasteners must be supplied by installer.
