Appleton NSB GRJT75 conduit outlet box – GRJT75 – is a 3/4-inch, Type GRJT (Type T) explosion‑proof conduit body for threaded metallic conduit systems. The enclosure is malleable iron, with an externally threaded body and an internally threaded cover, and it accepts three 3/4-inch hubs to route multiple conduits in a single box. This GRJT75 unit provides a rugged junction point for splices and terminations in industrial environments where explosion‑proof construction is required, keeping conduits and connections secure under demanding service conditions.
