Installation to Solid Concrete or Cinder Block
Make sure that wall plate (AA) is level, use it as a
templateto mark four mounting holes. The top
mountinghole should be 2.5" above the desired screen
center as shown in figure 4.1 on page 8. 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).Placewall 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
whenmounting the wall plate forequipment weighing
greaterthan 200 lbs.
• 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 meetASTM 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.
• Makesurethatthe supporting surface will safely support the combined load of the equipment and all attached hard-
wareand components.

custom fasteners must be supplied by installer.

• 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.).
