These heavy-duty earth anchors are used for securing poles, tower, trees, stages and other similar structures. We sell them into the arborist, tower rigging and stage rigging industries. They are known as helical anchors, earth anchors, earth augers and helix anchors. They are popular because they are both strong and economical, and install easily.
