DEHN Seam Clamp ZG 0.7-6mm for Lightning Protection and Earthing 365000

Roofers and lightning protection installers use the DEHN Seam Clamp ZG 0.7-6mm to connect round or flat conductors to standing seam metal roofs. It grips seams from 0.7 to 6 mm thick, providing a secure mechanical and electrical connection for earthing and lightning protection systems. The clamp body is stainless steel (V2A) for corrosion resistance, and the terminal is tinned copper for low contact resistance. It accommodates round conductors 8–10 mm in diameter or flat conductors up to 30 mm wide. Installation is tool-free: simply place the clamp on the seam and tighten the screw connection. Compliant with EN 62561-1, it is suitable for new builds and retrofits on metal roofs.
