The Jiujin D-iron Bracket with Secondary Swinging Clevis is an integrated solution engineered for critical articulation points in pole line infrastructure. The D-iron bracket offers a robust and stable base, firmly anchored to the utility pole, while the integrated swinging clevis provides the essential pivot to absorb mechanical stresses caused by conductor movement, wind, and ice loading. Manufactured from forged carbon steel and protected with a heavy-duty hot-dip galvanized coating, this assembly guarantees superior tensile strength and exceptional resistance to rust and corrosion. Produced directly at our Hebei factory, this unit ensures a perfect fit, simplified installation, and long-term, maintenance-free performance in electrical transmission and distribution systems.
