Drill two 1/4" (6 mm) dia. holes to a minimum depth of
2.5" (64 mm). Attach ceiling plate ( C) using two concrete
anchors and #14 x 2.5" wood screws ( H) as shown in
Illustration A and 1, 2, and 3 (below). 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 3 for flush mount installation.
Skip to step 4 for extension column installation.
Illustration A
Installation to Concrete Ceilings
ACC 203 (Alligator ® concrete anchors) are recommended.
• FOR DIRECT ATTACHMENT TO LOAD BEARING
CONCRETE ONLY! Concrete expansion anchors are
not intended for attachment to concrete ceilings cov-
ered 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
• Tighten wood screws so that ceiling 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
• When installing Peerless wall 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 Load Capacity of 50 lb (27 kg).
