Position wall bracket (A) at desired position on wall . Use wall
bracket (A), making sure that it is level, as a template to mark
holes. Drill three 1/4" (6 mm) dia. holes to a minimum depth of
2-1/2" (64 mm). Concrete must be 2000 psi density minimum.
Insert anchors (H) in holes flush with wall as shown in figure
1.1. Place wall bracket (A) over anchors and secure with three
#14 x 2-1/2" wood screws (G) as shown in figure 1.2. Make
sure wall bracket (A) is level and tighten all fasteners.

• Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the screws, greatly
reducing their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
• Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material as shown below. If mounting
to concrete wall covered with plaster/drywall is un-
avoidable, plaster/drywall (up to 5/8" thick) 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.
WARNING
Installation to Solid Concrete Surface
• 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 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 hard-
ware and components.
WARNING
Tighten all fasteners.
