Installation to Solid Concrete or Cinder Block
Use wall plate (D) as template to mark mounting
holes.Thetopmounting hole shouldbe6"abovethe
desired screen center as shown in figure 1.1 on page 5.
Drill three 5/16" (8 mm) dia. holes 3" (76.2 mm) deep as
shown in fig. 1.3. Insert anchors (F) in holes flush with
wall as shown (right). Place wall plate over anchors and
secure with 5/16 x 3" screws (E). 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 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
breakingoutthebackoftheholewhen entering a 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.
