Installation to Solid Concrete or Cinder Block
Make sure that wall plate (B) is level, use it as a
template to mark four mounting holes. The top
mounting hole should be 5.35" (136 mm) above the
desired screen center as shown in gure 1.1 on page
2. Drill four 1/4" (6 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Insert anchors (K) in holes
ush with wall as shown (right). Place wall plate over
anchors and secure with #14 x 2.5" screws (J). Level,
then tighten all fasteners.
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" 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" minimum from the side of the block. Cinder block must meet ASTM C-90 specica-
tions. 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.

Drill holes and insert anchors (K).
Place plate (B)over anchors (K) and secure with screws (J).
Tighten all fasteners.
• Always attach concrete anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other nishing material.
If mounting to concrete surfaces covered with
a nishing surface is unavoidable, the 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", custom fasteners must be
supplied by installer.
WARNING
B
• Tighten screws so that wall plate is 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.).
