Installation to Solid Concrete or Cinder Block
Make sure that wall plate (A) is level, use it as a
template to mark four mounting holes. The top
mounting slots should be located X" above the
desired display center as shown in fi gure 1.1 and
1.2 on page 4. Drill four 5/16" (8mm) dia. holes to a
minimum depth of 2.5" (64mm). Insert anchors (D) in
holes fl ush with wall as shown (right). Place wall plate
over anchors and secure with four wood screws (C).
Level, then tighten all fasteners.
• 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.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all at-
tached hardware and components.
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).
