Installation to Solid Concrete or Cinder Block
Mark the desired display center and use wall plate
template (wall plate) to mark mounting holes. Center
of display mounting plate will be .25" offset from
center of stud (mounting hole) as shown in figure
1.1 on page 5. The top mounting hole should be
6.23" (158mm) above the desired display center as
shown in figure 1.1. Drill four 5/16" (8mm) dia. holes
2.5" (64mm) deep as shown in figure 1.3. Insert
anchors (D) into holes flush with wall. Place wall
arm (A) over anchors and secure with four wood
screws (C) using #3 screwdriver bit (M). Level then
tighten all fasteners.
Insert four fastener caps (F) into wall plate mounting
holes.

• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35mm) 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" (25mm) minimum from the side of the block. Cinder block must meet ASTM
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 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
hardware and components.
• 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.).
• Always attach concrete expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to
concrete covered with plaster, drywall, or other
finishing material. If mounting to concrete surfaces
covered with a finishing surface is unavoidable (not
evaluated by UL), 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" (16mm), custom fasteners must be supplied by
installer (not evaluated by UL).
