Installation to Solid Concrete or Cinder Block
Make sure that wall plate (AA) is level, use it as a
template to mark six mounting holes. For ST670
models the top mounting slots should be 2.9"
(74mm) above the desired display center as shown
in fi gure 1.1 on page 5. For ST680 models the top
mounting slot should be 1.3" below the desired
display center. Drill six 5/16" (8mm) dia. holes to
a minimum depth of 2.5" (64mm). Insert anchors
(EE) in holes fl ush with wall as shown (right). Place
wall plate over anchors and secure with #14 x 2.5"
screws (DD). Level, then tighten all fasteners.

• 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 expansion anchors directly to load-
bearing concrete.
• Never attach concrete expansion 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"
(16mm), custom fasteners must be supplied by installer
(not evaluated by UL).

• 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 specifi 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.
• Two wood screws (DD) must be installed into wall plate (AA) in each segment as shown in detail 1, or product may fail.
• 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.
