The Stake Mate MegaPlate was designed specifically for heavy clusters of ground-mounted balloons that require enhanced stabilization in a variety of different landscaping conditions. Perfect for the DuraBalloon® Cluster Kit or keeping any other Pole Kit upright at all times in loose soil and/or extreme winds. The 6" diameter plate ensures your pole doesn't dig itself into the ground and three surrounding 8" X-Stakes limit any side to side movement of the kit. A center ball in the middle of the MegaPlate allows you to mount your aluminum spike vertical on sloped grades. Reusable Helium-free Pole Kits are intended to sway back and forth 24/7 in the wind so the center ball surrounding your spike prevents wear into the MegaPlate and can be replaced as needed. The average life of the MegaPlate center ball is over 2 years. This MegaPlate is easy to install and will keep your Pole Kits standing upright for years to come! Metal Ground Spike is sold separately.
