Installation to Solid Concrete and Cinder Block
B
When installing double stud wall plate 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 meet ASTM C-90 specifications. 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.
WARNING
Level and use wall arm assembly(
AA
) as template
to mark center of holes,make sure the correct dire
about installation of the wall arm assembly.
-ction
Drill four 10 mm dia. holes to a minimum depth of
3.3".Insert six concrete anchors(
M
) in holes flush
with wall as shown in
fig B.1.
Place wall arm asse
(
AA
) over anchors
-mbly
and secure with six hex
(
N
) and six washers (
C
) as shown
fig. B.2
and
in
fig.B.4
. Make sure wall arm assembly
is level, and tighten all fasteners see
fig.B.3.
Concrete anchors are
not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material as shown below. If mounting
to concrete wall covered with plaster/drywall is
unavoidable, plaster/drywall (up to 5/8" thick) must be
counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tighten-
ing screws. If plaster/drywall is thicker than
5/8", custom fasteners must be supplied by the installer.
WARNING
Tighten hex head bolts so that wall arm assembly
is firmly attached,but do not overtighten. Overtightening
can damage the screws, greatly reducing their holding
power.
