3-1/2" to 2-1/2" reducing bushings are used with threaded rigid or IMC conduits to reduce the size of female hubs in order to accommodate smaller sized conduits or male threaded hubs. Garvin Industries’ rugged steel construction maintains mechanical protection and solid grounding of the conduit to the designated electrical junction box or enclosure. Reducing bushings are zinc electroplated for excellent corrosion protection in damp locations.
