Keep your patio umbrella securely grounded with these umbrella stand weights, designed for steady support. The sand-fillable base stabilizer accepts a variety of fill materials, so you can customize the weight for your patio furniture. A wide-mouth opening makes loading and emptying quick and mess-free, while the convenient slide-in slot allows fast placement around your umbrella base. Built from rugged 900D Oxford fabric with a waterproof Pu layer, it is sun-proof and tear-resistant for long-lasting outdoor use. An adjustable securing strap tightens firmly for a snug hold, helping reduce shifting as the wind picks up. Reinforced carry handles make it easy to move the weights when rearranging your deck or storing them away. Compatible with offset, center-pole, and cantilever umbrellas, it's a versatile stability upgrade for patios, gardens, and poolside areas. The umbrella and cross stand is not included.
