For Concrete Walls
use wall arm (
W
), making sure
that it is level, as a template to mark holes. Drill 1/
4" (6 mm) dia. holes to a minimum depth of 2.5" (64
mm). Insert concrete anchors in holes flush with
wall as shown (right). Place wall arm (
W
) over
anchors and secure with #14 x 2.5" (6 mm x 65
mm) wood screws (
V
). Tighten all fasteners.

WARNING
• When installing BOSCH wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete
surface 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 hard-
ware and components.

Tighten all fasteners
• Tighten wood screws so that wall plate is firmly
attached, 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.).
• Make sure that mounting screws are anchored into the
center of the studs. The use of an "edge to edge" stud
finder is highly recommended.
WARNING
• Concrete anchors are
not
intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material. If mounting to concrete wall
covered with plaster/drywall is unavoidable, plaster/
drywall (up to 5/8" thick) must be counterbored as
shown below. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
