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 2-1/2" (64 mm). Insert anchors
(F) in holes fl ush with wall. Place wall arm assembly
(AA) over anchor and secure with wood screws
(D). Make sure wall arm is level, and tighten all
fasteners.

CINDER BLOCK

Installation to Solid Concrete and Cinder Block

Drill holes and insert anchors (F).

Place wall plate (AA) over anchors (F) and secure with screws (D).

Tighten all fasteners.

• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35mm) 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" (25mm) 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 wall will safely support four times 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
material. If mounting to concrete surfaces covered
with a fi nishing surface is unavoidable (not evaluated
by UL), the fi nishing surface must be counterbored
as shown below. Be sure concrete anchors do not
pull away from concrete when tightening screws. If
plaster/drywall is thicker than 5/8" (16mm), custom
fasteners must be supplied by installer (not evaluated
by UL).
