4-hole inspection connection, wire-wound B up to 50mm (aluminum) /AL/ AH03094

Lightning protection system inspection joint – reliability and safety

This inspection joint, made of aluminum, is designed to connect the lightning conductor wire to the roofing sheet. It allows for a connection in the range of conductors with a diameter of 8-10 mm and up to 50 mm, making it a versatile element in many installations. The solid construction and the use of stainless steel screws (4xM10x20) guarantee durability and corrosion resistance, and therefore – long-lasting and safe operation of the surge protection system.

Functionality and application

The AH Hardt inspection joint is a key element in lightning protection systems. Its main task is to enable the measurement of grounding resistance without the need to disconnect the conductors. This is extremely important for regular monitoring of the installation's efficiency and quick detection of potential problems. Mounting the joint in boxes or lightning protection pits provides easy access to the control point, which facilitates inspection and maintenance.
