Coupling Dowel

The coupling dowel is a critical component used to join multiple earth rods together, allowing for greater depth and improved grounding efficiency. This ensures that the earth rods can penetrate deep into the ground, where the soil is more conductive, creating a more effective grounding system. Made from high-strength materials like brass or copper alloys, coupling dowels maintain a secure, low-resistance connection between rods, ensuring that the integrity of the grounding system is preserved. This is especially important in areas with high soil resistivity or where deeper grounding is necessary.
