Place projector mount assembly (A) on ceiling as a
template and mark the center of the two mounting
holes. Drill two 5/16" (8 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Attach projector mount assembly
(A) using two concrete anchors (W), two fl at washers
(I), and two #14 x 2.5" wood screws (V) as shown.
NOTE: Mounting slots on projector mount assembly
allow for 30° (±15°) of swivel adjustment before fully
securing wood screw.
Tighten wood screws (V) using 3/8" (10 mm) socket
wrench, phillips screwdriver until projector mount
assembly (A) is fi rmly attached.

Installation to Concrete Ceilings
3
• 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.
WARNING
• Tighten wood screws fi rmly, but do not overtighten.
Overtightening can damage 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 fi nishing material. If
mounting to concrete surfaces covered with a fi nish-
ing surface is unavoidable, the fi nishing surface
must be counterbored as shown below. Be sure con-
crete 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.
