Wall plate (A) can be mounted to two studs that are 16" apart. Use a stud finder to locate the edges of the studs.
Use of 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. 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 (D) as shown in figure 1.2.
Skip to step 2 on page 6.
Installation to Double Wood Stud Wall
1
• 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 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. The use of an "edge to edge" stud finder
is highly recommended.
• When installing Peerless wall mounts on a wood stud wall covered with gypsum board (drywall), verify that the
wood studs are a minimum of 2" x 4" nominal size. Do not install over gypsum board thicker than 5/8".

Installation to Solid Concrete or Cinder Block
1Make sure that wall plate (A) is level, use it as a
template to mark four mounting holes. Drill four
5/16" (8 mm) dia. holes to a minimum depth of 2.5"
(64 mm). Insert anchors (E) in holes flush with wall
as shown (right). Place wall plate over anchors
and secure with #14 x 2.5" screws (D). Level, then
tighten all fasteners.
• When installing Peerless wall mounts on a concrete wall, the wall must be at least 8" thick with a minimum compres-
sive strength of 2000 psi.
• When installing Peerless wall mounts on a cinder block wall, the cinder blocks must meet ASTM C-90 specifications
and have a minimum nominal width of 8". Do not drill into mortar joints! Be sure to mount in a solid part of the block,
generally 1" (25 mm) minimum from the side of the block. 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.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.
WARNING
• Always attach concrete anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other finishing material.
WARNING
• Tighten screws so that wall plate is firmly attached,
but do not overtighten. Overtightening can damage
screws, greatly reducing their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).

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 tilt brackets to be attached. Place
tilt brackets (B and C) on back of screen as shown in fig. 2.2. Note: Be sure to attach tilt brackets with handles fac-
ing outward as in figure 2.2. Align tilt brackets to screen mounting holes as recommended by chart below. Attach the
tilt brackets to the back of the screen using the appropriate combination of screws, either M4 x 16 socket pin screws
(N), M6 x 12 mm socket pin screw (G), M6 x 20 socket pin screw (H), or M8 x 15 mm socket pin screw (J) with multi-
washers (I) as shown in figures 2.3 and 2.4. Verify that all holes are properly aligned, and then tighten screws using
security allen wrench (F).

NOTE: Repeat using right tilt

• Tighten screws so adapter brackets are firmly
attached. Do not tighten with excessive force.
Overtightening can cause stress damage to screws,
greatly reducing their holding power and possibly
causing screw 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
product may fail.

Mounting and Removing Flat Panel Screen
DETAIL 2 fig 4.1
For preset tilt angles use Increlok™ and for custom tilt
angle use ratchet handle.
INCRELOK™:The screen can be locked into a
pre-set tilt position of -5°, 0°, 5°, 10°or 15°. Use
locator hole to find tilt position hole and tilt screen to
align holes. Tighten IncreLok™ tilt locking screws on
both tilt brackets to lock tilt as shown in detail 2.
Ratchet Handle: Loosen ratchet handle (refer to step
3 for tension adjustment of handle). Push or pull from
top or bottom of screen to adjust tilt as shown in figure
4.1. The tilt can be adjusted to a maximum of 15°
forward or 5° backward.
Tension Adjustment of Ratchet Handle: Adjust
tension in tilt brackets (B & C) by rotating ratchet
handle. NOTE: If obstruction prevents ratchet handle
from rotating, pull handle out while turning will allow
handle to reposition without tightening. Release and
turn handle to tighten or loosen.
Mounting Screen: Ratchet handle must be in the
up or down position or interference will occur while
hooking tilt brackets to wall plate (A). Slowly hook tilt
brackets (B & C) onto wall plate (A) and swing screen
down as shown in fig. 3.1. Tilt bracket hooks must
fully engage wall plate. Using phillips screw driver or
security allen wrench (F), turn safety/security screws
on tilt brackets (B & C) clockwise till screw tip securely
contacts wall plate as shown in cross section.
Screen Adjustment: Screen can be adjusted
horizontally by loosening safety/security screws on
tilt brackets (B & C) three full turns. Adjust screen as
shown in figure 3.2. Tighten safety/security screws on
tilt brackets till screw tip securely contacts wall plate as
shown in cross section.
Removing Screen: To remove screen from mount,
loosen safety screws, swing screen away from mount,
and lift screen off of mount.
