Our durable ground spikes are made from extra heavy duty plate iron and steel tubing. All welds are "full line" welds, as opposed to inferior "spot" welded products. Finished with a thick silver powder-coating to ensure durability in the harshest weather conditions. This ground spike is designed to display Swooper Feather Flags or Wind-Free (Windless) Feather Flags in dirt or grassy areas and is designed to be used with our Deluxe 4-Piece Flagpole Sets.
