A drive rod is used to drive arrowhead anchors into the ground. The end of the drive rod is hollow and fits over the anchor's shank. The other end of the drive rod can then be pounded using a sledgehammer, fence post driver, or power jackhammer, until the cable eye attached to the anchor is 50mm (2") to 100mm (4") above the surface of the ground. After the anchor is driven, the drive rod is removed, leaving the anchor in the ground. The drive rod is made of steel and will last 2 installations. Reminder: NRG Systems offers its products exclusively to the wind energy industry. Anchors are sold for use with NRG Towers only.
