Appleton GRC100A Explosion Proof Conduit Outlet Box

Appleton GRC100A Explosion-Proof Conduit Outlet Box is a copper-free aluminum GR-type enclosure designed for hazardous locations and threaded metal conduit installations. The unit’s body features two 1" GRC hubs with hub locations on the sides, providing entry for two conduits while preserving a compact footprint. It offers 18 cubic inches of internal space and a 3.38" cover opening, paired with a Unilet-style cover for a secure seal. There are no knockouts pre-punched in the box, enabling field-entry customization without compromising enclosure integrity. As part of Appleton’s GR family, this explosion-proof, dust-ignitionproof conduit outlet box delivers rugged protection for wiring connections and remains compatible with standard 1" threaded conduits; the enclosure stands about 3-3/4 inches tall, making it suitable for tight installations where reliable protection is essential.
