Circular Sandbags — Stackable Rounded Weight Bags
The gold standard ballast bag for single post applications.
Circular Sandbags are designed to wrap securely around posts, poles, or stand bases, providing 25 lb of weight (50 lbs with steel shot fill) that can be stacked to meet any stability requirement. Whether used to secure patio umbrellas, stabilize microphone stands, add weight to signage, or keep outdoor heaters upright in heavy winds, these rounded weight bags offer unmatched flexibility and convenience.
Made from heavy-duty Cordura® fabric and sewn with double-stitched seams, each bag is built for years of daily use—indoors or outdoors. A sturdy handle makes them easy to carry, while the compact circular shape allows you to stack multiple bags for higher ballast. Available empty (for local fill) or pre-filled with clean chip sand or steel shot, they’re ready to adapt to nearly any application.
