Appleton GRCA50 Explosionproof Conduit Outlet Box

The Appleton GRCA50 Unilets CA-style dust-ignitionproof explosionproof conduit outlet box is a 1/2-inch, malleable-iron GR-series enclosure built for hazardous locations, featuring three 1/2-inch GRC hubs and an 18‑cu‑in internal capacity to accommodate pull-and-splice wiring in sealed conduit runs. Designed for use with threaded metallic conduit systems, it carries a copper-free aluminum cover and includes an internal ground screw and an O‑ring to provide a raintight seal when paired with sealing covers. Its dimensions measure 3-3/4 inches high by 3-3/4 inches wide by 2-1/4 inches deep, with a 3.38-inch cover opening, and the housing is triple-coated (zinc electroplate, chromate, epoxy powder coat) for corrosion resistance. Part of Appleton's GR/GRF family of conduit outlet boxes, the GRCA50 is designed to meet dust-ignitionproof and explosionproof requirements for hazardous environments and is suitable for industrial installations that require a durable, code-compliant enclosure for wiring and conduits.
