An extension ground is another element of vertical grounding. It allows you to extend the earthing to any length. Insert the (cone) of the base earth electrode into the hole of the extension earth electrode, building a deep earthing system. It is possible to insert a special tip F825020 or F825024 into the earth electrode hole, where the extension earth electrode becomes the base earth electrode.
