Installation to Solid Concrete and Cinder Block
Level and use wall plate as template to mark center
of holes. Drill two 5/16" (8 mm) dia. holes to a
minimum depth of 2.5" (64 mm). Insert anchors (B)
in holes fl ush with wall. Place wall mount (A) over
anchors and secure with wood screws (H). Make
sure wall mount is level, and tighten all fasteners.

• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35 mm) 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" (25 mm) 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 supporting surface will safely support the combined load of the equipment and all attached
hardware and components.
WARNING
• 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 expansion anchors directly to
load-be aring concrete.
• Never attach concrete expansion anchors to concrete
covered with plaster, drywall, or other fi nishing mate-
rial. If mounting to concrete surfaces covered with a
fi nishing surface is unavoidable, the fi nishing surface
must be counterbored as shown below. Be sure con-
crete anchors do not pull away from concrete when
tightening screws. If plaster/drywall is thicker than
5/8" (16 mm), custom fasteners must be supplied by
installer. (not evaluated by UL)
