Install Outer Channel to Ceiling Plate

Attach outer channel (BB) to ceiling plate (AA) using four M6 x 10 mm socket pin screws (II) as shown. Tighten

screws with 4 mm security wrench (L).

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.

Skip to step 3

• 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

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.
