Appleton BJ41012 Rigid Expansion Bonding Jumper

Appleton BJ41012 is a 14-inch bonding jumper engineered for 1 to 1-1/4 inch trade-size rigid or IMC conduit runs, creating a continuous electrical bond across long conduit sections and expansion joints when used with XJ series expansion couplings (such as XJ100-4 or XJ125-4) that accommodate up to 4 inches of movement. It combines a malleable iron clamp with a copper braid to maintain grounding continuity between segmented conduit runs, supporting NEC 250.98 bonding requirements. The assembly is finished in hot-dip galvanized coating for corrosion resistance in demanding environments, and its 14-inch length is designed to span expansion joints and extended runs. The BJ41012 is UL 467 listed, reflecting its suitability for grounding applications in conduit systems, and it is sold as part of Appleton’s line of expansion-coupling accessories. Appleton, an Emerson brand, offers this bonding jumper to ensure reliable bonding continuity across joints in rigid conduit installations, aligning with the capabilities described in XJ expansion coupling documentation and typical distributor listings.
