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 concrete
covered with plaster, drywall, or other finishing mate-
rial. 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 concrete
when tightening screws. If plaster/drywall is thicker
than 5/8" (16 mm), custom fasteners must be sup-
plied by installer (not UL approved).
WARNING
NOTE: Wall installation with models EXC, EXC-S
and EXC-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 (A) using two concrete anchors (J),
two #14 x 2.5" wood screws (H) and two washers (O)
as shown in figure 2.6. Tighten wood screws (H) until
ceiling/wall plate (A) 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 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.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all attached
hardware and components.
