Installation to Concrete Ceilings
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 2-1/2" (64mm). Attach
projector mount assembly (A) using two concrete
anchors (G), two fl at washers (E), and two #14 x
2-1/2" wood screws (F) as shown in Illustration A
and 1, 2 and 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
hardware and components.
WARNING
• 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).

Overtightening can damage the screws, greatly
reducing their holding power.
