Bronze U Bolt Clamps, Rod to Cable Guv Clamps, Copper U Bolt Clamps
We are one of the leading manufacturers and exporters of Bronze U Bolt Clamps, Rod to Cable Guv Clamps, and Copper U Bolt Clamps from India. We have been supplying precision-engineered grounding and lightning protection fittings to the world market for many decades. Our wide range of clamps is used across electrical earthing, lightning protection, and grounding systems. These clamps are known for their robust construction, corrosion resistance, precision engineering, and adherence to international standards like BS EN 12163, ASTM B62/B124, DIN 43670, and JIS H3250. Designed for long-term durability in both industrial and infrastructure applications, our U Bolt and Guv-type clamps are manufactured using high-conductivity Copper and corrosion-resistant Bronze alloys. With decades of experience in exporting to the USA, Europe, and the Middle East, our clamps ensure electrical continuity and mechanical reliability across a variety of installations. They can be with Stainless Steel (304 and 316 grades) Nuts and U Bolts or one made from Bronze or Copper.

Bronze U Bolt Clamps
Bronze U Bolt Clamps are used to provide a secure and corrosion-resistant connection between Copper tapes or cables and rods. Manufactured from high-strength Bronze alloys such as CuZn40Pb2 (CW617N), CuSn5Zn5Pb5-C (ASTM B62), and other international grades, these clamps offer excellent electrical conductivity and superior mechanical strength. Our clamps are machined to close tolerances using CNC and VMC machines for consistent thread pitch, parallelism, and fit. These clamps are ideal for outdoor installations, offering weatherproof performance in aggressive environments. Finishes include natural Bronze, tinned, or nickel-plated depending on customer preference.
Rod to Cable Clamps – Guv Type
Rod to Cable Clamps, also known as Guv Clamps, are essential components in bonding Copper cables to earth rods. The Guv type design offers a saddle-like clamp structure where the cable lies within a grooved surface, held firmly by a top pressure plate and secured with Bronze or Stainless Steel U bolts. These clamps are often used in lightning protection systems and grounding networks. Conforming to BS 7430 and IEEE standards, they are designed to withstand high fault currents and ensure secure bonding over years of service. We offer custom sizing for rod diameters from 12mm to 25mm and cable sizes from 25 sq.mm to 120 sq.mm.
Bronze Guv Clamps
Bronze Guv Clamps are manufactured from Leaded Gunmetal (LG2), CuSn5Pb5Zn5-C (ASTM B62), and other high-grade Bronze alloys. Known for their rugged mechanical strength, they are often used in heavy industrial grounding applications. These clamps feature an integral design to allow better load distribution, and are secured with Stainless Steel fasteners. These are preferred in installations where galvanic compatibility, anti-corrosion performance, and high conductivity are critical.
Copper Guv Clamps
Copper Guv Clamps are used where maximum conductivity is required, especially in sensitive or high-performance grounding applications. Manufactured from 99.9% pure Electrolytic Copper (ETP grade – ASTM B187), these clamps are ideal for installations in refineries, data centers, and renewable energy plants. We offer annealed or hard-drawn versions based on end-use. These are precision-machined and supplied with optional tinned or nickel coatings to resist oxidation in marine or high-humidity locations.
Copper U Bolt Clamps
Copper U Bolt Clamps are designed to hold Copper tapes or cables securely to a flat or round surface. Available in sizes from 25x3mm up to 50x6mm for tapes, and 12mm to 20mm for rods, these clamps are ideal for safe current discharge in earthing systems. Threaded portions are carefully rolled and machined to minimize cross-threading and enhance mechanical strength. Available finishes include natural, electro-tinned, or powder-coated.
U Bolt Cable Clamps
U Bolt Cable Clamps are universal grounding clamps designed for multipurpose bonding of rods, cables, or tapes to structural steel or rebar. These are supplied in both single and double U bolt designs for enhanced rigidity. Preferred materials include Bronze, Copper, and Stainless Steel for marine applications. Used extensively in substations, telecom towers, wind turbines, and solar PV grounding applications, these clamps are tested to sustain mechanical pull force of over 200 Nm.
