• Always attach concrete anchors directl to load-
bearing concrete.
• Never attach concrete anchors to concrete covered
with plaster, drywall, or other finishing material. If
mounting to concrete surfaces covered with a finishing
surface is unavoidable, the finishing surface must be
counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tighten-
ing screws. If plaster/drywall is thicker than 5/8",
custom fasteners must be supplied by installer.
