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
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.
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 2.5" (64 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. Place wall plate over anchors and
secure with #14 x 63.5 mm screws (CC). Level, then
tighten all fasteners.
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-be aring concrete.
• Never attach concrete expansion anchors to concrete
covered with plaster, drywall, or other fi nishing mate-
rial. If mounting to concrete surfaces covered with a
fi nishing surface is unavoidable (not UL evaluated),
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/dry-
wall is thicker than 5/8" (16 mm), custom fasteners
must be supplied by installer (not evaluated by UL).
