• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35 mm) 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" (25 mm) minimum from the side of the block. Cinder block must meet ASTM
C-90 specications. 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 four times the combined load of the equipment and all attached hardware
and components.
• Tighten screws so that wall plate is rmly 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 nishing mate-
rial. If mounting to concrete surfaces covered with a
nishing surface is unavoidable, the nishing surface
must be counter bored as shown below. Be sure con-
crete anchors do not pull away from concrete when
tightening screws. If plaster/drywall is thicker than
5/8" (16 mm), custom fasteners must be supplied by
installer.
For Concrete Surfaces use wall plate as a template,
level and mark center of mounting holes. Drill 5/16" (8
mm) dia. holes to a minimum depth of 2.5"
(64 mm). Insert anchors (C) into holes ush with wall,
place wall plate over anchors and secure with #14 x 2.5”
hex head wood screws (A) as shown right. Make sure
wall plate is level, and tighten all fasteners.
