Installation to Solid Concrete or Cinder Block
Determine and mark the desired screen center on the
wall. Place wall plate template (wall arm) on wall with
top mounting slots 9" (229mm) above desired screen
center as shown in fi gure 2.1 on page 5. Level wall
plate template (wall arm) on wall and mark center of
four mounting holes making sure that the mounting
holes. Drill four 3/8" (10mm) dia. pilot holes to a depth
of 3" (76mm). Insert anchors (D) into holes fl ush with
wall as shown (right). Place wall arm over anchors and
secure with 5/16 x 3" screws (C). Level, then 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 supporting surface will safely support the combined load of the equipment and all attached hard-
ware 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-bearing 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,
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.
