Installation to Solid Concrete or Cinder Block
Determine and mark with a pencil, the desired center
ofscreenon wall. Measure 7" (177 mm) above desired
center of screen and draw a horizontal line to locate
placement of wall plate template.Align top of template
(topof wall plate) with horizontal line. Leveltemplate
(wallplate) on wall and mark center of six mounting
holes. Drill six 5/16" (8 mm) dia. holes 3" (76.2 mm)
deep. Insert anchors (F) in holes flush with wall as
shown(right).Placewallplate (D) over anchors and
secure with six 5/16" x 3" screws (E) as shown in fig.
2.3. Level wall plate, 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 meetASTM C-90 specifications.
It is suggested that a standard electric drill on slow setting is used to drill the hole instead of a hammer drill to avoid
breakingoutthebackoftheholewhenenteringa void or cavity.
• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Makesure that the supporting surface will safely supportthe combined load of the equipment and allattached hard-
wareand components.

• Neverattach concrete anchors toconcretecovered
withplaster, drywall, or other finishing material. If

• Tighten screws so that wall plate is firmly attached,
butdo not overtighten.Overtighteningcan damage
