Installation To Concrete Ceilings - NEC NP2200 Installation And Assembly Manual

Installation to Concrete Ceilings

3 Drill two 1/4" (6 mm) dia. holes to a minimum depth of
2.5" (64 mm). Attach projector mount assembly (A)
using two concrete anchors (G), two flat washers (E),
and two #14 x 2.5" wood screws (F) as shown in
Illustration A and 1, 2, and 3 (below). Tighten wood
screws (F) using 3/8" (10 mm) socket wrench until
projector mount assembly (A) is firmly attached.
WARNING
• Tighten wood screws firmly, 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.).
WARNING
• Installer must verify that the wall will safely support
four times the combined weight of all attached equip-
ment and hardware.
Skip to step 6.
WARNING
• Concrete anchors are not intended for attachment to
concrete ceiling covered with a layer of plaster,
drywall, or other finishing material. If mounting to
concrete ceiling covered with plaster/drywall is un-
avoidable, plaster/drywall (up to 5/8" thick) must be
counterbored as shown below. If plaster/drywall is
thicker than 5/8", custom fasteners must be supplied
by installer.
