What type of connectors is recommended for penetrating roofs or walls?

Thru-roof or thru-wall connectors are essential components in lightning protection systems, primarily because they ensure a safe and effective path for lightning currents when the system has to traverse barriers such as roofs or walls. Using these connectors helps maintain the integrity of the lightning protection system by minimizing the risk of damage to the structure. They are specifically designed to accommodate the installation through different building materials while providing the necessary weather resistance and electrical continuity that is critical for effective lightning protection.

These connectors are constructed to handle the physical stress and environmental conditions that occur at penetrations, ensuring durability and reliability. Inappropriate connections can lead to poor grounding and increase the risk of lightning damage or system failure. As such, the use of thru-roof or thru-wall connectors is a best practice in ensuring a secure and compliant lightning protection installation.
