Installing to Interior Corner 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.
• 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.
WARNING
BB
Efig. 1.2
Wall plates (B) can be mounted to one or 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 on both walls. NOTE: Depending on placement of studs on wall corners, mounting to
two studs may not be possible.
Determine the distance from the corner of the wall to the inside edge of the wall plates (B) using the equation
below and detail 1 to get distance "X". NOTE: If mounting speaker mounts to sides of corner mount, screen can
be no larger than 40". See page 10 for speaker mount installation.
Measure "X" distance from corner of wall and mark location for inside edge of wall plate. The top mounting slots
of wall plate should be located 3.44" (87 mm) above the desired screen center as shown in fig 1.1. Level wall
plate, align to location marked for inside edge of wall plate and mark four slots in alignment with center of studs.
Repeat for opposite wall plate. Drill 5/32" (4 mm) dia. holes to a minimum depth of 2.5" (64 mm). Make sure that
wall plates are level and secure using #14 x 2.5" wood screws (E).

Measure 1" (25 mm) from corner of wall and mark location for inside edge of wall plate. The top mounting slots of
wall plate should be located 3.44" (87 mm) above the desired screen center as shown in fig 1.3. Level wall plate,
align to location marked for inside edge of wall plate and mark four slots in alignment with center of studs. Repeat

Installing to Exterior Corner Wood Stud Wall

• 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.).

Installing to Interior Corner Concrete or Cinder Block Wall
1
• 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
specifications. 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.
WARNING
Determine the distance from the corner of the wall to
the inside edge of the wall plate (B) using the equation
and detail 1 on page 4 to get distance "X".
NOTE: If mounting speaker mounts to sides of corner
mount, screen can be no larger than 40". See page 10
for speaker mount installation.
Measure "X" distance from corner of wall and
mark location for inside edge of wall plate. The top
mounting slots of wall plate should be located 3.44"
(87 mm) above the desired screen center as shown in
fig 1.1 on page 4. Level wall plate (B), align to location
marked for inside edge of wall plate and mark four
slots in alignment with center of studs. Repeat for
opposite wall plate. Drill 5/16" (8 mm) dia. holes to a
minimum depth of 2.5" (64 mm). Insert anchors (F) in
holes flush with wall as shown (right). Place wall plate
over anchors, make sure that wall plates are level and
secure using #14 x 2.5" wood screws (E).
• Always attach concrete anchors directly to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other finishing material.
If mounting to concrete surfaces covered with
a finishing surface is unavoidable, the finishing
surface must be counterbored as shown right.
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.
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.).
