• Always attach concrete expansion anchors directly to load-bearing concrete.
• Never attach concrete expansion 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 (not evaluated ny UL), the fi nishing surface must be counterbored as shown below.
Be sure concrete anchors do not pull away from concrete when tightening screws. If plaster/
drywall is thicker than 5/8" (16mm), custom fasteners must be supplied by installer (not evaluated
by UL).
• Tighten screws so that projector mount 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.).
