Installation to Solid Concrete or Cinder Block
Make sure that wall plate (A) is level, use it as a
template to mark four mounting holes. The top
mounting slots should be located 7" (177 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 (D) in
holes flush with wall as shown (right). Place wall plate
over anchors and secure with wood screws (C). Level,
then tighten all fasteners.

SOLID CONCRETE
CINDER BLOCK
• 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 specifica-
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.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all at-
tached hardware and components.
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.).
WARNING
• Always attach concrete anchors directly to load-
bearing concrete.
• Never attach concrete 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", custom fasteners must be supplied by
installer (not evaluated by UL).
