Installation to Extension Column / Ceiling Plate
NOTE: Refer to accompanying instructions with ceiling plates (sold separately) for installing these models to
2
ceiling.
Screw projector mount assembly (A) onto extension column as shown in figure 2.1.
NOTE: For 3/4" extension columns, reducer ACC 913 (not included) will be required as shown in figure 2.2. Tighten
swivel stop screw against extension column, flush mount tube or reducer using 4 mm security allen wrench (B) as
shown in figure 2.3.
NOTE: Swivel stop screw is used to jam against threads of extension column, flush mount tube or reducer to
prevent any excess movement of projector mount assembly (A). Do not overtighten screw; overtightening screw will
damage threads making it difficult to separate products.

Installation To Wood Joist Ceilings
WARNING
• Tighten wood screws so that projector mount assembly is firmly attached, 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.).
• Make sure that mounting screws are anchored into the center of the studs. The use of an "edge to edge" stud finder is
highly recommended.
Place projector mount assembly (A) on ceiling as a template and mark the center of the two mounting holes. Make
2
sure that the mounting holes are in the center of the wood joist. Drill two 5/32" (4 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Attach projector mount assembly (A) with two #14 x 2.5" (6 mm x 65 mm) wood screws (F)
and two flat washers (E) as shown in figure 2.4 or figure 2.5 depending on joist orientation. Tighten wood screws (D)
using 3/8" (10 mm) socket wrench, phillips screwdriver or 10mm open end wrench until projector mount
assembly (A) is firmly attached.
Skip to step 3.

Installation to Concrete Ceilings
WARNING
• 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.).
Place projector mount assembly (A) on ceiling as a
2
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 (G), two
flat washers (E), and two #14 x 2.5" wood screws (F)
as shown in fig. 2.6 and 1, 2 and 3 (right). Tighten
wood screws (F) using 3/8" (10 mm) socket wrench,
phillips screwdriver or 10mm open end wrench until
projector mount assembly (A) is firmly attached.
NOTE: It is the responsibility of the installer to
verify that the ceiling will safely support the
combined load of all attached hardware and
components.
Skip to step 3.
WARNING
• Concrete anchors are not intended for attachment to
concrete ceiling covered with a layer of plaster,
drywall, or other finishing material. If mounting to
concrete ceiling covered with plaster/drywall is unavoidable, plaster/drywall (up to 5/8" thick) must be
counterbored as shown below. If plaster/drywall is
thicker than 5/8", custom fasteners must be supplied
by installer.
