Place projector mount assembly (A) on ceiling as a
template and mark the center of the two mounting holes.
Drill two 1/4" (6 mm) dia. holes to a minimum depth of 2.5"
(64 mm). Attach projector mount assembly (A) using two
Alligator

concrete anchors (M), two flat washers (K), and
two #14 x 2.5" wood screws (L) as shown in Illustration A
and 1, 2 and 3).
NOTE: Mounting slots on projector mount assembly allow
for 30° (±15°) of swivel adjustment before fully securing
wood screws.
Tighten wood screws (L) using 3/8" (10 mm) socket or
open end wrench or phillips screwdriver until projector
mount assembly (A) is firmly attached.
Installation to Concrete Ceilings

• 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.

• Always attach concrete anchors directly to load-bearing
concrete.
• Never attach concrete anchors to concrete 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 concrete when tightening screws. If plaster/drywall is
thicker than 5/8", custom fasteners must be supplied by
installer (not UL approved).
• 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.).
