Installation to Solid Concrete or Cinder Block
• 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 hard-
ware and components.
Use wall arm (A) as template to mark mounting holes.

The top mounting hole should be 7.54" (192 mm) above
the desired screen center as shown in figure 1.1 on
page 4. Drill three 5/16" (8 mm) dia. holes 2.5" (64 mm)
deep as shown in fig. 2.1. Insert anchors (D) into holes
flush with wall as shown. Place wall arm over anchors
and secure with three wood screws (C) using #3
screwdriver bit (K). Level, then tighten all fasteners.
Insert three fastener caps (F) into wall plate mounting
holes.
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.
