Drill two 1/4" (6 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Attach ceiling plate (Y)
using two concrete anchors (V) and #14 x 2.5"
wood screws (U) as shown in Illustration A and
1, 2, and 3 (below). Tighten all fasteners.

• 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 specifi cations.
• 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.
• Never exceed the Maximum UL Load Capacity.
WARNING
• Always attach concrete expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to con-
crete covered with plaster, drywall, or other fi nishing
material. If mounting to concrete surfaces covered
with a fi nishing surface is unavoidable (not evaluated
by UL), the fi nishing surface must be counterbored
as shown below. If plaster/drywall is thicker than
5/8", custom fasteners must be supplied by installer
(not evaluated by UL).

• Tighten wood screws so that ceiling plate is fi rmly
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.).
