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 wall will safely support the combined load of the equipment and all attached hardware and compo-
nents.
Level and use wall plate as template to mark center of
1
holes.
Drill two 1/4" (6 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Insert anchors (F) in holes flush
with wall as shown in fig 1.2. Place wall arm assembly
(AA) over anchor and secure with wood screws (D) as
shown in figure 1.3. Make sure wall arm is level, and
tighten all fasteners. See figure 1.4.
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 tightening screws. If plaster/drywall
is thicker than 5/8", custom fasteners must be supplied
by installer. (Not evaluated by UL)
