• 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 nish-
ing surface is unavoidable (not evaluated by UL), the
fi nishing surface must be counterbored as shown be-
low. 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 (not evaluated by UL).
