Position wall plate ( B) at desired position on wall . Use
wall plate ( B), making sure that it is level, as a template
to mark holes. Drill four 1/4" (6 mm) dia. holes to a mini-
mum depth of 2-1/2" (64 mm). Concrete must be 2000
psi density minimum. Insert anchors ( K) in holes flush
with wall as shown in figure 1.3. Place wall plate ( B) over
anchors and secure with four #14 x 2-1/2" (6 mm x 65
mm) wood screws ( I) as shown in figure 1.4. Make sure
wall plate is level and tighten all fasteners.

• Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the screws, greatly re-
ducing their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
WARNING
• 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 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 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 as shown below. If mount-
ing to concrete wall covered with plaster/drywall is
unavoidable, plaster/drywall (up to 5/8" thick) must
be counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tight-
ening screws. If plaster/drywall is thicker than
5/8", custom fasteners must be supplied by installer.
