Installation to Wood Stud Walls
Use a stud nder to locate the edges of the stud.
Use of an edge-to-edge stud nder is highly
recommended. Based on its edges, draw a vertical
line down the stud’s center. Place wall plate (A)
on wall as a template. Mark the center of the four
mounting holes. Drill four 5/32” (4 mm) dia. holes
2-1/2” (65 mm) deep. Secure wall plate (A) to wood
stud using four #14 x 2-1/2” wood screws (I) 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 wall plate is 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. The use of an “edge to edge” stud nder
is highly recommended.
• Hardware provided is for attachment of mount through standard thickness drywall or plaster into wood studs.
Installers are responsible to provide hardware for other types of mounting situations.

• 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 speci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.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.
Installation to Solid Concrete or Cinder Block
Make sure that wall plate (A) is level, use it as a
template to mark four mounting holes. Drill four
1/4” (6 mm) dia. holes to a minimum depth of
2.5” (64 mm). Insert anchors (O) in holes ush with
wall as shown (right). Place wall plate over anchors
and secure with #14 x 2.5” screws (I). Level, then
tighten all fasteners.
WARNING
• Always attach concrete anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other nishing material. If
mounting to concrete surfaces covered with a nish-
ing surface is unavoidable, the nishing surface must
be counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tight-
ening screws. If plaster/drywall is thicker than 5/8”,
custom fasteners must be supplied by installer.
WARNING
• Tighten screws so that wall plate is rmly 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 at, 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 adapter brackets (C) on back of screen, align to holes, and center on back of screen as shown below. Attach
the adapter brackets to the back of the screen using the appropriate combination of screws, multi-washers, and
spacers as shown in gure 4.1 or 4.2.
NOTE: Top and bottom holes on screen must always be used.
Verify that all holes are properly aligned, and then tighten screws using a phillips screwdriver.

Installing Adapter Brackets
Notes:
• The number of fasteners used will vary,
depending upon the type of screen.
• Multi-washers and spacers may not be
used, depending upon the type of screen.
• Use the corresponding hole in the multi-
washer that matches your screw size.
• Tighten screws so adapter brackets are rmly 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.
WARNING
NOTE: For at back screens proceed to step 4-1. For bump-out or recessed back screen skip to step 4-2.

for a full screen compatibility chart for this mount.
Begin with the shortest length screw, hand thread through multi-washer and adapter bracket (C) into screen as
shown below. Screw must make at least three full turns into the mounting hole and t snug into place. Do not over
tighten. If screw cannot make three full turns into the screen, select a longer length screw from the bafed fastener
pack. Repeat for remaining mounting holes, level brackets and tighten screws.
NOTE: Spacers may not be used, depending upon the type of screen.
