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 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 speci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 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-bearing concrete.
• Never attach concrete expansion anchors to concrete
covered with plaster, drywall, or other nishing mate-
rial. If mounting to concrete surfaces covered with a
nishing surface is unavoidable, the 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)
