Appleton NSB-T47 Condulets And Unilets

Appleton NSB-T47 Condulets & Unilets are 1-1/4 in hub, Form 7, Type T conduit outlet bodies built for three-hub, three-way intersections in rigid metal conduit (RMC) and IMC runs. Constructed from Grayloy iron, they wear a triple-coated finish (zinc electroplate, chromate, epoxy powder coat) for durability in harsh electrical environments. The unit provides roughly 20 cubic inches of internal volume across its three hubs, supporting pulling and splices. The form 7 unilet measures about 7.44 inches long, 3.19 inches wide, and 2.31 inches high, with tapered FNPT connections for secure, removable access to conductors. UL 514A and UL 514B listings apply, and the body is designed for use with RMC/IMC rigid conduits to support pulling, splicing, and maintenance at a three-way junction; some listings note compatibility with NEMA FB-1 enclosure requirements. Typical applications include industrial control panels, manufacturing facilities, and commercial electrical installations where a three-way conduit junction is necessary, providing a dedicated pull point without detouring conduit paths.
