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 
(D), two fl at washers (F), and two #14 x 2.5" wood 
screws (C) as shown. 

Note: Mounting slots on projector mount assembly 
allow for 30° (±15°) of rotation before fully securing 
wood screw.

•  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.).

•  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).

•  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.

Drill holes and insert anchors (D).

Place plate (A) over anchors (D) and secure with screws (C).

Tighten all fasteners.
