 Make sure that the supporting surface will safely support the combined load of the equipment and all attached hardware and
components.
WARNING
 Tighten screws so that double stud wall plate is firmly attached, but do not overtighten. Overtightening can damage
the screws,greatly reducing their holding power.
 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
Wall arm assembly(AA) must be mounted onto two wooden studs,with center to center distances more than
12". Using a stud finder, locate and mark the edges of the wood stud used in mounting this product. Use of an
edge to edge stud finder is highly recommended. Use a level to draw two vertical lines down the center of the stud.
Use wall arm assembly(AA)as template to mark center of holes along the vertical line.Make sure the correct
direction about installation of the wall arm assembly. Drill six 6 mm(1/4") dia. holes 3.3" deep.Attachwall arm
assembly (AA) to wall using six hex head screws(N)and six washers(C)as shown in fig. A.1

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.
