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" 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.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.
Make sure that wall plate (AA) is level, use it as a
1
template to mark four mounting holes. The top
mounting hole should be 2.5" above the desired screen
center as shown in figure 1.1 on page 4. Drill four 1/4"
(6 mm) dia. holes to a minimum depth of 2.5" (64 mm).
Insert anchors (EE) in holes flush with wall as shown
(right). Place wall plate over anchors and secure with
#14 x 2.5" screws (DD). Level, then tighten all
fasteners.
NOTE: Six holes and six sets of fasteners are required
when mounting the wall plate for equipment weighing
greater than 200 lbs.
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 tighten-
ing screws. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
