Make sure that wall plate (A) is level, use it as a
template to mark four mounting holes. Drill four 1/4"
(6 mm) dia. holes to a minimum depth of 2.5"
(64 mm). Insert anchors (D) in holes fl ush with wall as
shown in fi gure 1.2. Place wall plate over anchors and
secure with #14 x 2.5" screws (C). Level, then 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 specifi ca-
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.

• Tighten screws so that wall plate is fi rmly attached,
but do not overtighten. Overtightening can damage
screws, greatly reducing their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).•
Always attach concrete anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other fi nishing material. If
mounting to concrete surfaces covered with a fi nish-
ing surface is unavoidable, the fi nishing surface 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.
