Installation to Solid Concrete or Cinder Block Wall
• When installing 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 ham-
mer 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.

Make sure that wall plate (C) is level, use it as a
template to mark four mounting holes. Drill four
5/16" (8 mm) dia. holes to a minimum depth of 2.5"
(64 mm). Insert anchors (F) in holes ush with wall
as shown. Place wall plate (C) over anchors and
secure with four #14 x 2.5" screws (E). Level, then
tighten all fasteners.
• 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 material. If mounting to concrete surfaces
covered with a nishing surface is unavoidable,
the nishing surface must be counter bored as
shown below. Be sure concrete 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.
