Installing Tilt Brackets
Refer to Screen Compatibility Chart to determine the proper fasteners to use.
NOTE: Referto page 4 for adjustments of top extensionbracket.
To prevent scratching the screen, set a cloth on a flat, level surface that will support the weight of the screen. Place
screen face side down. If screen has knobs on the back, remove them to allow the adapter brackets to be attached.
Place tilt brackets (BB and CC) on back of screen.Align to holes, and center on back of screen as shown in figure
2.1.Attach the tilt brackets to the back of the screen using the appropriate combination of screws, multi-washers, and
spacers as shown in figure 2.3. NOTE: Be sure to attach tilt brackets with knobs facing outward as in figure
2.1.
NOTE:Top and bottom mounting holes must be used for attaching brackets. Middle holes should also be used where
thefasteners and screens allow.
Verifythatall holes are properly aligned, and then tighten screws usingaphillipsscrewdriver.
NOTES:
• Alwaysuse multi-washers when attaching
tilt brackets (BB and CC) to your screen.
• Use the corresponding hole in the multi-
washer that matches your screw size as
showninfigure 2.2.
• Spacersmay not beused,depending upon
the type of screen.

Overtighteningcan cause stress damage to screws,
greatlyreducing their holding powerand possibly
causingscrew heads to become detached. Tighten to
40 in. • lb (4.5 N.M.) maximum torque.
• If screws don't get three complete turns in the screen
inserts or if screws bottom out and bracket is still not
tightly secured, damage may occur to screen or

With tape measure, measure the outside to outside of the brackets on the back of your screen. If width of the tilt
brackets on back of the screen is over 18-1/2" shown in figure 3.1, using a wrench, attach wing bracket (GG) to
center bracket using two 1/4 serrated flanged locknuts (FF) as shown in figure 3.2. If width of the brackets on back
of the screen is over 30-3/8", using a wrench, attach second wing bracket (GG) to center bracket using two 1/4
serratedflanged locknut (FF)as shown in figure 3.3.
CAUTION: If mounting to two studs on 16" centers, and using the three plate configuration, A STUD
MUST BE SKIPPED in the middle so distance between studs is 32".

Installation to Double Wood Stud Wall
NOTE: Ifmountingequipmentweighinggreaterthan 200 lbs, triple stud mounting is strongly recommended.
Skip to page 8
Wall plate (AA) can be mounted to two studs that are 16" apart. Use a stud finder to locate the edges of the studs.
Useof an edge-to-edge stud finder is highly recommended. Based on their edges, draw a vertical line down each
stud’s center. Place wall plate on wall as a template.The top mounting slots should be 2.5" above the desired
screen center as shown in figure 4.1. Level plate, and mark the center of the four mounting holes. Make sure that the
mounting holes are on the stud centerlines. Drill four 5/32" (4 mm) dia. holes 2-1/2" (65 mm) deep. Make sure that
the wall plate is level, secure it using four #14 x 2.5" wood screws (DD) as shown in figure 4.2.
NOTE: Wall plate may be mounted up to 4" (102 mm) off center as shown in figure 4.1.
Skip to step 5.
• Installermust verify that the supporting surface will safely support the combined loadofthe equipment and all attached
hardwareandcomponents.
• Tightenwood screws so that wall plate is firmly attached,butdo not overtighten. Overtightening can damage the
screws,greatly reducing their holdingpower.
• Never tighten in excess of 80 in. • lb (9 N.M.).
• Make sure that mounting screws are anchored into the center of the stud. The use of an "edge to edge" stud finder is
highlyrecommended.

Installation to Solid Concrete or Cinder Block
Make sure that wall plate (AA) is level, use it as a
templateto mark four mounting holes. The top
mountingholeshould be 2.5" above the desired screen
center as shown in figure 4.1 on page 7. Drill four 1/4"
(6 mm) dia. holes to a minimum depth of 2.5" (64 mm).
Insert anchors (EE) in holes flush with wall as shown
(right).Placewall plate over anchors and secure with
#14 x 2.5" screws (DD). Level, then tighten all
fasteners.
NOTE: Six holes and six sets of fasteners are required
whenmounting the wall plate for equipment weighing
greaterthan200lbs.
• 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 meetASTM 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.
• Makesurethat the supporting surface will safely support the combined load of the equipment and all attached hard-
wareand components.
