Installation to Wood Joist Ceilings or Wood Stud Walls
NOTE: Wall installation with models PRS-EXC, PRS-EXC-S and PRS-EXC-W is not available.
Use a stud finder to locate the edges of the stud or joist. Use of an edge-to-edge stud finder is highly
recommended. Based on its edges, draw a vertical line down the stud's or joist’s center. Place ceiling/wall plate
(AA) on wall or ceiling as a template, making sure that the two mounting slots are on the centerline.
For ceiling installation: Opening on outer channel (BB) indicates front of mount. Use the correct mounting slots
on the ceiling/wall plate depending on ceiling joist orientation as shown in figure 2.1 and figure 2.2. Mounting slots
on ceiling plate allow for 45° (±22.5) of rotation before securing to joist.
For wall installation: Opening on outer channel (BB) indicates top of mount.
Mark the center of the two mounting holes. Drill two 5/32" (4 mm) dia. holes 2-1/2" (64 mm) deep. Secure
ceiling/wall plate (AA) to wood stud or joist using two #14 x 2-1/2" wood screws (C) and two 1/4" washers (F)
as shown.

• Installer must verify that the supporting surface will safely support the combined load of the equipment and all
attached hardware and components.
• Tighten wood screws so that ceiling/wall plate 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 stud or joist. The use of an "edge to edge" stud
finder is highly recommended.
• Hardware provided is for attachment of mount through standard thickness drywall or plaster into wood studs or
joists. Installers are responsible to provide hardware for other types of mounting situations (not evaluated by UL).

Installation to Concrete Ceilings or Concrete/Cinder Block Walls
NOTE: Wall installation with models PRS-EXC,
PRS-EXC-S and PRS-EXC-W is not available.
Place ceiling/wall plate (AA) on ceiling or wall as a
template. NOTE: Place ceiling/wall plate according
to position of opening in outer channel (BB) as
shown in figure 2.4. or figure 2.5. Drill two 5/16"
(8 mm) dia. holes to a minimum depth of 2.5"
(64 mm). Attach ceiling/wall plate (AA) using two
concrete anchors (D), two #14 x 2.5" wood screws
(C) and two 1/4" washers (F) as shown in figure 2.6.
Tighten wood screws (C) until ceiling/wall plate (AA)
is firmly attached.

• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete
thickness in the hole to be used for the concrete anchors. Do not drill into mortar joints! Be sure to mount in a solid
part of the block, generally 1" minimum from the side of the block. Cinder block must meet ASTM C-90 specifica-
tions. It is suggested that a standard electric drill on slow setting is used to drill the hole instead of a hammer drill to
avoid breaking out the back of the hole when entering a void or cavity.
• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all at-
tached hardware and components.

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.).
• Always attach concrete expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to
concrete covered with plaster, drywall, or other
finishing material. If mounting to concrete surfaces
covered with a finishing surface is unavoidable (not
evaluated by UL), the finishing 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" (16 mm), custom fasteners must be supplied by
installer (not evaluated by UL).

Installing Inner Channel and Routing Cables
3NOTE: Be certain holes on inner channel (CC) face in the same direction of opening on outer channel (BB).
NOTE: Cables must be removed from projector before routing through channels. If cables are not removable from
projector, routing through channels is not an option.
Guide projector cables into openings in channels then insert inner channel (CC) into outer channel (BB) as shown
in figure 3.1 or 3.3.
Position inner channel (CC) to the desired extended position and secure using two M6 x 12 mm socket pin
screws (HH) through clamp plate (DD) and into inner channel (CC) as shown in figure 3.2 or 3.4.

in figure 4.1 and attach to horizontal mounting plate (FF) using two M5 x 16 mm socket pin screws (GG), four flat
washers (F) and two locknuts (KK).
Installing PRS projector mount with ceiling installation: Attach vertical mounting plate (EE) to PRS projector
mount (A) using two M5 x 16 mm socket pin screws (GG), four flat washers (F) and two locknuts (KK) as shown in
figure 4.2.
NOTE: Placing washer (F) and nut (KK) combination on inside of PRS projector mount first while attaching

NOTE: The projector you are installing may differ in appearance from the sample illustrated below.
Place projector upside down. Locate adapter plate (B) with notch facing forward as close to projector center of
gravity as possible without covering any mounting holes. Loosen channels with 4 mm security allen wrench (I),
and if there are only three mounting holes remove fourth channel. Using one channel for each mounting
hole, position feet of channels over mounting holes as shown below. IMPORTANT:: If projector does not have
at least three mounting holes, do not use this adapter plate.
NOTE: Some projectors have feet which can be removed and the corresponding threaded insert can be used
for a mounting hole.
NOTE: Once channels are in position retighten fasteners.
