Installation to Solid Concrete or Cinder Block
• When installing Peerless wall mounts on a concrete wall, the wall must be at least 8" thick with a minimum compres-
sive strength of 2000 psi.
• When installing Peerless wall mounts on a cinder block wall, the cinder blocks must meet ASTM C-90 specifications
and have a minimum nominal width of 8". 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. 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.
• Never attach expansion anchors to concrete or cinder block covered with plaster, drywall or other finishing material.
• Two wood screws (C) must be installed into wall plate (A) in each segment as shown in detail 1, or product may fail.
Make sure that wall plate (A) is level, use it as
1
a template to mark six mounting holes. The top
mounting slots should be located X" above the
desired display center as shown in figure 1.4 and
1.5 on page 5. Drill six 5/16" (8mm) dia. holes to a
minimum depth of 2.5" (64mm). Insert anchors (D) in
holes flush with wall as shown (right). Place wall plate
over anchors and secure with six wood screws (C).
Level, then tighten all fasteners.
WARNING
• 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 anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other finishing material.
If mounting to concrete surfaces covered with a
finishing surface is unavoidable (not evaluated by
UL), 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", custom fasteners
must be supplied by installer (not evaluated by UL).
