• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete
surface 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 four times the combined load of the equipment and all attached hardware
and components.
Installation to Solid Concrete,
Cinder Block, and Brick Walls
®
Two sets of Alligator
concrete anchors (ACC 203) are required.
Use wall bracket (A), making sure that it is level, as a tem-
plate to mark holes. Drill 1/4" (6 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Insert anchors in holes flush with wall
as shown (right). Place wall bracket (A) over anchors and
secure with #14 x 2.5" (6 mm x 65 mm) wood screws. Tighten
all fasteners.
WARNING
• Tighten wood screws firmly, 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. If mounting to concrete wall
covered with plaster/drywall is unavoidable, plaster/
drywall (up to 5/8" thick) must be counterbored as
shown below. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
