Installation to Solid Concrete or Cinder Block
Make sure that wall plate (AA) is level, use it as
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 fi gure 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 fl ush with
wall as shown (right). Place wall plate over anchors and
secure with #14 x 2.5" wood screws (CC). Level, then
tighten all fasteners.

• 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
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-bearing concrete.
• Never attach concrete expansion anchors to con-
crete 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" (16 mm), custom
fasteners must be supplied by installer. (not evaluated
by UL)
