• 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.

• Tighten screws so that wall plate is firmly 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 finishing material. If

mounting to concrete surfaces covered with a finish-

ing surface is unavoidable, the finishing 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.

as shown.

Place wall plate over anchors and secure with

six #14 x 2.5" screws (
