Thru-Roof and Thru-Wall Assemblies

Thru roof and thru wall products are used when systems are to be concealed but only when the air terminal is to be exposed or when using a typical lightning protection base is impractical due to the structure or space allowed to apply the base. Thru wall assemblies are designed to be used when the conductor is ran inside of a wall. They are designed to connect the downleads to the grounding system by drilling a hole through the wall or foundation and making the connection to the grounding system.
