This is an anchor stake with a difference. Using a standard 1/2" (13mm) wrench, you can turn this 16" long screw-in stake into the ground. Once it is in place, it takes a tremendous amount of force to pull it out again. It is ideal for anchoring tree guy wires, greenhouses, large dogs, etc. The steel loop at the top provides a convenient attachment point. If carefully installed, it can be mowed over. These are the stakes used to anchor soccer nets in Europe. Made in France.
