Installation to Solid Concrete and Cinder Block
• 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
hardware and components.
Level and use wall plate as template to mark center
1
of holes. Drill two 1/4" (6 mm) dia. holes to a
minimum depth of 2.5" (64 mm). Insert anchors (B)
in holes flush with wall as shown in fig 1.1. Place
wall mount (A) over anchors and secure with wood
screws (H) as shown in figures 1.2 and 1.4. Make
sure wall mount is level, and tighten all fasteners.
See figure 1.3.
WARNING
• Tighten screws so that wall plate is firmly attached,
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.).
WARNING
• 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
unavoidable, 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
(not UL evaluated).
