CONCRETE CEILING
Drill hole and insert anchor
Place ceiling plate over anchor and secure with screw
After repeating step one tighten all fasteners
• 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 studs. The use of an "edge to edge" stud
finder is highly recommended.
WARNING
• When installing Peerless wall mounts on concrete, verify that you have a minimum of 1 5/8" of actual concrete surface
in the 1/4" diameter hole to be used for the concrete anchors. Do not drill into mortar joints! Concrete must meet
ASTM C-90 specifications.
• 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 weight of mount and projector.
• Never exceed the Maximum Load Capacity of 50 lb (22.7 kg).
WARNING
Drill two 1/4" (6 mm) dia. holes to a minimum depth of
2.5" (64 mm). Attach ceiling plate (A) using two
concrete anchors (F) and two #14 x 2.5" wood screws
(B) as shown in Illustration A and 1, 2, and 3 (below).
Tighten all fasteners.
