Lightning Protection

Protect electrical systems from lightning strikes on structures up to seventy-five feet tall. When replacing or adding components to an existing system, choose components that match your existing material. For a new system, choose components of the same material.

Rod bases can be mounted horizontally or vertically.

Wire clamps fold around the wire.

Bonding plates electrically bond your system to a metallic object.

Parallel connectors accept lightning wire and rods.

Joint compounds are recommended for use in corrosive environments. Apply at connection points.
