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.
