Steel City® switch and outlet boxes are protected from rust and corrosion by zinc-galvanizing. All clamps and other component parts are electrogalvanized separately, before assembly in the box, to ensure corrosion protection of every surface. Steel City® galvanized finish meets the requirements of Underwriters Laboratories, Inc. and Federal Specifications.
Steel City® conduit KOs have standard trade size dimensions. KOs are uniform and true for attachment of cable or conduit connectors. Pryouts for cable entrance are slotted — a twist with a screwdriver removes them. KOs and Pryouts are precision stamped to permit easy removal, but remain sufficiently strong and sturdy when not removed.Outlet Box Ears
Mounting ears support the box independent of the electrical system attachments. Switch boxes have a fixed ear for old work installations. Ears for plaster are set 1A6″ forward of the box face in position for old work (modernization), except where specifically noted.Tapped Holes for Grounding
All Steel City® boxes have a 10-32 tapped hole in the bottom of the box for attaching separate ground wire.
