Please Note - An Earthing Coil Cord is also needed to attach the Grounding Rod and Cord to your Earthing product. You will find it here - Earthing Coil Cord.
The Grounding Rod is placed directly in the earth and the extension cord connects to your Earthing product via a coil cord. You can run the cord through a window or under a door and into the ground outside. Ground rods can be used with all Earthing products and as an alternative to connecting through your power outlets.
