Costway 18.5" Umbrella Base Weight, 90 LBS Sand-fillable Bags with Weatherproof Fabric - Black HCST14540

Keep your patio umbrella securely grounded with heavy-duty umbrella stand weights made for dependable, all-season support. Constructed from rugged 900D Oxford fabric with a waterproof PU inner coating, they're designed to resist tearing, sun exposure, and outdoor conditions for long-lasting use. Fill the umbrella base stabilizer with up to 90 lbs of sand, gravel, stones, or soil to boost anti-tip stability in windy weather. The detachable 2-piece design wraps neatly around most poles and bases, while fastening buckles help hold everything in place and minimize shifting during outdoor dining or poolside lounging. 2 large filling openings make refills and material changes faster and cleaner. When you're done, integrated side handles make the weights easy to carry, store, or take on the go. Compatible with offset, cantilever, and center-pole umbrellas, the sand-fillable bags can also help steady patio heaters and other outdoor gear. The umbrella and cross stand is not included.
