FRONT OF
MOUNT
Place projector mount assembly (A) on ceiling as a
template and mark the center of the two mounting
holes. Drill two 5/16" (8mm) dia. holes to a minimum
depth of 2.5" (64mm). Attach projector mount
assembly (A) using two concrete anchors (G), two fl at
washers (E), and two #14 x 2.5" wood screws (F) as
shown.
Note: Mounting slots on projector mount assembly
allow for 30° (±15°) of rotation before fully securing
wood screw.
Tighten wood screws (F) using 3/8" (10mm) socket
wrench or phillips screwdriver until projector mount
assembly (A) is fi rmly attached.
Skip to step 5.
Installation to Concrete Ceilings
• Tighten wood screws fi rmly, 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.).
WARNING
3
• 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 nishing surface is unavoidable (not evaluated by
UL), the fi nishing 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 evaluated by UL).
WARNING
• 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
hardware and components.
