‡ Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the bolt, greatly reducing
its holding power.
WARNING
‡ Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material. If mounting to concrete wall
covered with plaster/drywall is unavoidable, 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.
