Installation to Solid Concrete or Cinder Block Wall
• 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 concrete expansion anchors to concrete or cinder block covered
with plaster, drywall or other finishing material.
Use wall plate (A), making sure that it is level, as
1
a template to mark holes. The top mounting slots
should be located at your desired display center.
Use the masonry bit to drill 3/8" (10mm) dia. holes
to a minimum depth of 3" (76mm). Insert anchors
(W) in holes flush with wall as shown (right). Place
wall plate (A) over anchors (W) and secure with
5/16 x 3" wood screws (O) and washers (P).
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 expansion anchors directly
to load-bearing concrete.
WARNING
1
Drill holes and insert anchors (W).
2
Place plate (A) over anchors (W) and secure with screws (O) and
washers (P).
3
Tighten all fasteners.
