DEHN 478129 NIRO V4A M10 Universal Connection Clamp for Round 8-10 mm and Flat 30 mm Conductors

In lightning protection and earthing systems, connecting round and flat conductors securely in harsh environments is a challenge. The DEHN 478129 NIRO V4A M10 universal connection clamp solves this by providing a corrosion-resistant, high-strength connection for round conductors 8-10 mm diameter and flat conductors up to 30 mm width. Made from stainless steel V4A (AISI 316L), it withstands aggressive conditions including saltwater exposure, ensuring long-term reliability.

Who is it for

This clamp is intended for electricians, lightning protection installers, and maintenance professionals who need robust conductor connections in outdoor, industrial, or coastal environments. It suits applications in lightning protection, earthing, and equipotential bonding where corrosion resistance is critical.
