Installation to Concrete Ceilings
• 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.
Drill two 5/16" (8 mm) dia. holes to a minimum depth
1
of 2.5" (64 mm). Insert anchors (S) in holes flush
with wall. Place ceiling plate (B) over anchors and
secure using two #14 x 2.5" screws (Q).
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 for flush mount installation.
Skip to step 3 for extension column installation.
WARNING
• 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.).
• 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 (not evaluated
by UL), 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 supplied by installer (not evalu-
ated by UL).
