Installation to Solid Concrete or Cinder Block
NoTE: Wall arm assembly (A) must be mounted to
wall using inner mounting holes.
Make sure that wall arm assembly is level and use
wall plate as a template to mark four mounting holes.
Use Wall Arm Assembly Mounting Detail on page 4 to
determine wall arm ( A) Placment.
Drill four 5/16" (8 mm) dia. holes to a minimum depth
of 2.5" (64 mm). Insert anchors ( D) in holes flush
with wall as shown. Place wall arm assembly over
anchors and secure with wood screws ( C). Level,
then tighten all fasteners. Insert eight fastener caps
( H) into mounting holes. NoTE: Be sure arrow is
pointing up when mounting wall arm assembly ( A) to
wall as shown in figure 1.2.

• 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 specifications. 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 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 expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to
concrete covered with plaster, drywall, or other
finishing material. If mounting to concrete surfaces
covered with a finishing surface is unavoidable,
the finishing 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" (16 mm), custom
fasteners must be supplied by installer.
