Installation to Concrete Ceilings
Drill two 5/16" (8 mm) dia. holes to a minimum depth
of 2.5" (64 mm). Attach ceiling plate (B) using two
concrete anchors (H) and #14 x 2.5" wood screws (E)
as shown in Illustration A and 1, 2, and 3 (below).
Tighten all fasteners.
• Tighten wood screws fi rmly, but do not overtighten.
Overtightening can damage the bolt, greatly reducing
its holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
WARNING
• Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other fi nishing material. If mounting to concrete
wall covered with plaster/drywall is unavoidable, plas-
ter/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 (not
evaluated by UL).
