NOTE: ACC203 (Alligator
concrete anchors are not
included) are recommended.
Drill two 1/4" (6 mm) dia. holes to a minimum depth of
2.5" (64 mm). Attach ceiling plate (G) using two concrete
anchors and #14 x 2.5" wood screws (F) as shown in
Illustration A and 1, 2 and 3. Tighten all fasteners.
IMPORTANT: It is the responsibility of the installer to
verify that the ceiling will safely support the
combined load of all attached hardware and
components.
Skip to step 2.
Installation to Concrete Ceilings
• FOR DIRECT ATTACHMENT TO LOAD BEARING
CONCRETE ONLY! Concrete expansion anchors are
not intended for attachment to concrete ceilings
covered with a layer of plaster, drywall, or other
finishing material. If mounting to concrete ceiling
covered with plaster / drywall is unavoidable, plaster /
drywall must be counterbored as shown below.
WARNING
• When installing Peerless mounts on concrete, verify that you have a minimum of 1 5/8" of actual concrete surface in
the 1/4" diameter hole to be used for the concrete anchors. Do not drill into mortar joints! Concrete must meet ASTM
C-90 specifications.
• 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 hard-
ware and components.
• Never exceed the Maximum UL Load Capacity of 50 lb (22.7 kg).

• 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.).
