Grounding Rod Clamps

Connect bare-copper ground wire to grounding rods.

Clamps with a floating pressure bar distribute pressure evenly over a large area, which creates more contact area for grounding.

UL 467 clamps meet a standard for direct burial.

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.
