Installation to Wood Joist Ceilings or Wood Stud Walls
WARNING
• 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 fi rmly 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
fi nder 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).
NOTE: Wall installation with models PRG-EXC, PRG-EXC-S and PRG-EXC-W is not available.
2
Use a stud fi nder to locate the edges of the stud or joist. Use of an edge-to-edge stud fi nder 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 fi gure 2.1 and fi gure 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" (65 mm) deep. Secure
ceiling/wall plate (AA) to wood stud or joist using two #14 x 2-1/2" wood screws (D) and two 1/4" washers (F)
as shown in fi gure 2.3.

Installation to Concrete Ceilings or Concrete/Cinder Block Walls
WARNING
• 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 specifi ca-
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 attached hardware and components.
NOTE: Wall installation with models PRG-EXC,
2
PRG-EXC-S and PRG-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 fi gure 2.4. or fi gure 2.5. Drill two 5/16"
(8mm) dia. holes to a minimum depth of 2-1/2"
(64 mm). Attach ceiling/wall plate (AA) using two
concrete anchors (C), two #14 x 2-1/2" wood
screws (D) and two 1/4" washers (F) as shown in
fi gure 2.6. Tighten wood screws (D) until ceiling/
wall plate (AA) is fi rmly attached.
WARNING
• 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
• Always attach concrete anchors directly to loadbearing 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).

Installing Inner Channel and Routing Cables
Note: 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 fi gure 3.1 or 3.3.
Position inner channel (CC) to the desired extended position and secure using two M6 x 12 mm socket pin

Attaching Adapter Plate to Projector
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.

all screws, while keeping the center of gravity. Be sure that adapter plate (B) is straight. Adjust the feet of the
channels to keep the adapter plate level. Tighten all screws with 4 mm security allen wrench (I) while keeping the
center of gravity. If M3 x 8 mm screws (J) are used, tighten using 2 mm security allen wrench (H).
NOTE: Projectors will require different size screws for mounting. Use a combination of screws (J, K, L or M) and
foot adjustment that will result in channels of adapter plate (B) fi tting tightly against projector. Important: In order
to properly engage the threads in the mounting holes, the screw must be turned at least 3 full turns.
NOTE: If using screw (J), place washer (G) between screw (J) and foot of channel.
