Installation to Solid Concrete or Cinder Block
1 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). Insert
anchors (EE) in holes flush with wall as shown
(right). Place wall plate over anchors and secure
with #14 x 2.5" screws (CC). Tighten all fasteners.
• When installing Westinghouse wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual con-
crete 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 meet ASTM 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 wall will safely support four times the combined load of the equipment and all attached hardware
and components.

• Always attach concrete expansion anchors directly to
load-bearing concrete.
• Never attach concrete expansion anchors to con-
crete covered with plaster, drywall, or other finishing
material. If mounting to concrete surfaces covered
with a finishing surface is unavoidable, the finishing
surface must be counterbored as shown below. If
plaster/drywall is thicker than 5/8", custom fasteners
must be supplied by installer.
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.).
