The Metal Ground Spike is the strongest of all the ground mounting options. It is the top choice for flag pole mounting, DuraBalloon® Cluster Kits in extreme winds, or MegaBalloon Kits. The 33” zinc-coated steel rod features a flat metal ring preventing your pole from boring down into the ground. A pointed tip makes installing this spike a breeze in the majority of landscaped conditions. This spike also has a machined race in its side allowing for the included C-clip to secure your pole in place. The Metal Ground Spike is also compatible with the Universal MegaPlate which enhances your product stability and is sold separately.
