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 wall will safely support four times the combined load of the equipment and all attached hardware
and components.
Make sure that wall plate (AA) is level, use it as
1
a template to mark four mounting holes. The top
mounting hole should be 4.6" (117 mm) above the
desired screen center as shown in figure 1.1 on page
4. Drill four 5/16" (8 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Insert anchors (DD) in holes
flush with wall as shown (right). Place wall plate over
anchors and secure with #14 x 2.5" screws (CC).
Level, then tighten all fasteners.
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 con-
crete 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 con-
crete when tightening screws. If plaster/drywall is
thicker than 5/8" (16 mm), custom fasteners must be
supplied by installer.
