Appleton Electric JBDX75L Iron Box Enclosure Unit

Appleton's JBDX75L Unilets conduit outlet box is a round, malleable-iron enclosure in the JB Series designed for four 3/4-in tapped openings. It features mounting lugs for secure attachment to panels, walls, or equipment, and a 4.5-inch outside diameter with a 2-1/16-inch internal depth, delivering about 23 cubic inches of internal space for small relays, timers, or terminal blocks. The 3/4-inch hub size accepts standard conduit connections, and the unit provides two close-up plugs to seal any unused outlets. This robust enclosure is triple-coated with zinc electroplate, chromate conversion, and epoxy powder coat to deliver corrosion resistance in harsh industrial environments. Designed for use with threaded rigid metal conduit (RMC) and IMC, the JBDX75L supports reliable wiring entries while maintaining a compact footprint suitable for control panels, machine enclosures, and compact junctions. Its malleable-iron construction provides mechanical strength to withstand vibration and impact in demanding applications, making it a practical choice for facilities needing a standardized 4-outlet conduit box in a compact round form factor.
