This explosionproof, dust-ignitionproof sealing hub can be used to seal vertical conduit riser at switch gear and motor control centers, sheet metal structures, or cast boxes and enclosures. It can also be used as a male thread enlarger or conduit hub in an ordinary location. A smooth, rounded integral bushing in each hub protects the conductor insulation. Accurately tapped and tapered threads provide tight, rigid joints and ground continuity.
