Appleton Electric Company GR-Form-3 Conduit Outlet Box

Appleton GR-Form-3 Conduit Outlet Box is a GR-series 2" NPT hub enclosure designed for use with threaded conduit in hazardous locations, delivering a Form 3-rated outlet box for explosion‑proof and dust‑ignition‑proof service. It is UL Listed and CSA Certified for use in Class I, II, and III classified locations, with a smooth, rounded integral bushing in each hub to protect conductor insulation, and it includes an internal ground screw and an O‑ring sealing system for reliable enclosure integrity. The Form 3 rating corresponds to larger conduit feeds (2" size in this model) and is compatible with GR and GRF covers to meet NEMA 3/4, dust and moisture exposure requirements in industrial environments. Typical applications include lighting fixtures and control wiring in chemical processing, oil and gas, and other hazardous facilities that demand robust, weather‑resistant electrical terminations.
