Appleton FS-1-100 1 Gang Malleable Iron Device Box

Appleton FS-1-100 is a 1-gang, shallow-depth malleable-iron device box designed for mounting switches and receptacles in industrial environments that use threaded conduit. It measures 4.56 in high by 2.81 in wide and 2.00 in deep, providing a compact enclosure with ridge-top construction for rugged service. Crafted from malleable iron and finished with a triple-coat (zinc electroplate, chromate and epoxy powder coat) for corrosion resistance, the box uses 1-inch hubs (two 1 in hubs) for conduit entries and is intended for use with threaded rigid metal conduit. It carries UL 514A listing (UL file E2527) and CSA C22.2 No. 18.1, aligning with NEMA FB-1 guidelines. The FS-1-100 designation marks this shallow 1-gang cast-hub box in Appleton's FS family, built to handle housings for typical wall-switch or outlet installations in industrial or commercial facilities.
