Installing to Exterior 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
specifi cations. 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
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 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
fi g 1.3 on page 5. 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 fl ush 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 fi nishing material.
If mounting to concrete surfaces covered with
a fi nishing surface is unavoidable, the fi nishing
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 fi 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.).
