Installation to Solid Concrete or 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 specifi ca-
tions. 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.
Determine the mounting location of wall plate (B)

using the formula in step one. Make sure that wall
plate is level, use it as a template to mark two
mounting holes. Drill two 5/16" (8 mm) dia. holes to a
minimum depth of 2.5" (64 mm). Insert anchors (D) in
holes fl ush with wall as shown (right). Place wall plate
over anchors and secure with #14 x 2.5" screws (E).
Level, then tighten all fasteners.
WARNING
• Tighten screws so that wall plate is fi 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 anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other fi nishing material.
If mounting to concrete surfaces covered with a
fi nishing surface is unavoidable (not evaluated by
UL), the fi nishing 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", custom fasteners
must be supplied by installer (not evaluated by UL).
