Lightning protection system inspection joint – reliability and durability

This inspection joint, made of stainless steel, is designed to connect the lightning protection wire to the roofing sheet. It allows checking the grounding resistance without disassembling the installation elements, which significantly facilitates the maintenance and diagnostics of the surge protection system. It is a key element of every lightning protection installation, ensuring its proper functioning and safety.

The joint is compatible with wires with a diameter of 8 mm to 40 mm, and its construction based on M8 and M10 screws (4xM8x20, 1xM10x16, 2xM8x20) guarantees a solid and durable connection. Made entirely of acid-resistant stainless steel (grade 0H18N9), it provides corrosion resistance and long-term reliability even in harsh weather conditions.
