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 concrete anchors (D), two
flat washers (F), and two #14 x 2.5" wood screws (C)
as shown in Illustration A and 1, 2, and 3.
Note: Mounting slots on projector mount assembly
allow for 30° (±15°) of rotation before fully securing
wood screw.
Tighten wood screws (C) using 3/8" (10 mm) socket
wrench or phillips screwdriver until projector mount
assembly (A) is firmly attached.
Skip to step 5.

• 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 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 tighten-
ing screws. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer (not
UL approved).
