SOLID CONCReTe
CINDeR BLOCK
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" (35mm) 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" (25mm) 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 four times the combined load of the equipment and all attached hardware
and components.

• Tighten screws so that wall plate is firmly 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
finishing material. If mounting to concrete surfaces
covered with a finishing surface is unavoidable,
the finishing 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" (16mm), custom
fasteners must be supplied by installer.
WARNING
Make sure that wall plate (
A
) is level, use it as a
template to mark four mounting holes. Drill four 5/16"
(8mm) dia. holes to a minimum depth of 2.5" (64mm).
Insert anchors (
K
) in holes flush with wall as shown
(right). Place wall plate over anchors and secure with
#14 x 2.5" screws (
I
). Level, then tighten all fasteners.
