Our X-Stand (Cross Base) is compatible with our Swooper Feather Flags and Wind-Free Feather Flags. This base is constructed from heavy duty plate and tubular steel and is finished with a weather-resistant black powder coating to withstand the elements. The base comes in 3 pieces: 2 cross pieces and 1 tube which has a screw that connects through the three components to form the finished x-stand. This feather flag accessory is ideal for displaying your flag set in level areas with solid grounding areas such as on the sidewalk, at a trade show, and much more. A sand bag is required for indoor and outdoor applications to provide the base with the needed support and stability.
