DEHNclip Equipotential Bonding Clamp 372219 Horizontal Stainless Steel for Round 8-10mm and Flat 30x3.5mm Conductors

Equipotential bonding and earthing connections on structural steel or earth electrodes often suffer from corrosion or unreliable contact over time. The DEHNclip 372219 solves this by providing a low-resistance, corrosion-resistant clamp made entirely of stainless steel (NIRO). It clips onto the mounting surface and secures either round conductors from 8 to 10 mm diameter or flat conductors up to 30 x 3.5 mm with an M8 screw connection. The horizontal orientation suits installations where the conductor runs parallel to the mounting plane.

Who is it for

Electricians and lightning protection installers who need a durable, maintenance-free bonding clamp for main equipotential bonding bars, earth electrodes, or structural steel in outdoor or harsh environments.

Main features

• Stainless steel (NIRO) construction for high corrosion resistance and UV stability.
• Accepts round conductors Ø 8–10 mm or flat conductors 30 x 3.5 mm.
• M8 screw connection ensures a secure, low-resistance bond.
• Clip-on installation method speeds up mounting without special tools.
• Horizontal mounting orientation for parallel conductor routing.
