Installation to Solid Concrete or Cinder Block Wall
• 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 speci¿ cations. 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 supporting surface will safely support the combined load of the equipment and all attached
hardware and components.
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 À ush 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 ¿ 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 expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to
concrete covered with plaster, drywall, or other
¿ nishing material. If mounting to concrete surfaces
covered with a ¿ nishing surface is unavoidable (not
evaluated by UL), the ¿ 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" (16mm), custom fasteners must be supplied by
installer (not evaluated by UL).
