Overview

The Panduit GPC2-2D-L Bronze Grounding Clamp is a high-strength, direct burial-rated grounding solution designed for bonding copper conductors to iron pipes in utility, industrial, and commercial grounding systems. Cast from electrolytic bronze, this clamp delivers reliable electrical continuity with superior corrosion resistance, making it ideal for harsh environments including direct burial in earth or concrete. The GPC2-2D-L accommodates a conductor size range from #10 solid to #2 stranded AWG, ensuring compatibility with a wide variety of grounding applications while reducing inventory requirements. The clamp features a 1 1/4" to 2" iron pipe size (IPS) range and includes a 2.22" (56.4mm) pipe clamp screw for secure attachment. The spacer plate design prevents direct contact between the conductor and mounting surface, enhancing long-term performance. Certified to cULus 467 for grounding and bonding, this clamp meets rigorous safety standards for direct burial applications. With high-strength silicone bronze hardware, the GPC2-2D-L provides durable, low-resistance connections that maintain integrity over time. Whether used in utility grounding grids, water pipe bonding, or meter shunt applications, this clamp delivers dependable performance in critical electrical safety systems.
