Position wall plate (AA) on wall so that upper slots are 4-5/8"
above desired center of screen. Use wall plate (AA), making
sure that it is level, as a template to mark holes. Drill four 1/4"
(6 mm) dia. holes to a minimum depth of 2-1/2" (64 mm).
Concrete must be 2000 psi density minimum. Insert anchors
(EE) in holes flush with wall as shown (right). Place wall plate
(AA) over anchors and secure with #14 x 2-1/2" (6 mm x 65
mm) wood screws (DD). Make sure wall plate is level and
tighten all fasteners.

• Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the screws, greatly
reducing their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
WARNING
•When installing 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 meetASTM C-90 specifica-
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.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached
hardware and components.

• Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material as shown right. If mounting
to concrete wall covered with plaster/drywall is
unavoidable, plaster/drywall (up to 5/8" thick) must
be counterbored as shown right. 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.
