Installation to Concrete Ceilings or Concrete/Cinder Block Walls
• Always attach concrete expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to con
-
crete covered with plaster, drywall, or other finishing
material. If mounting to concrete surfaces covered
with a finishing surface is unavoidable, the finishing
surface must be counterbored as shown below. Be
sure concrete anchors do not pull away from con
-
crete when tightening screws.
If plaster/drywall is
thicker than 5/8" (16 mm), custom fasteners must be
supplied by installer (not UL approved).
WARNING
NOTE: Wall installation with models PPC, PPC-S
and PPC-W is not available.
Place ceiling/wall plate (
A
) on ceiling or wall as a
template.
Note:
Place ceiling/wall plate according
to position of opening in outer channel (
B
) as shown
in figure 2.4. or figure 2.5. Drill two 1/4" (6 mm) dia.
holes to a minimum depth of 2.5" (64 mm). Attach
ceiling/wall plate using two concrete anchors (
I
), two
washers (
W
) and two #14 x 2.5" wood screws (
H
)
as shown in figure 2.6. Tighten wood screws until
ceiling/wall plate is firmly attached.

• Tighten wood screws firmly, 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.).

• When installing Peerless wall mounts 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 specifica
-
tions. 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.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all at
-
tached hardware and components.
