Made of four stackable Hdpe weight plates that snap together without tools, this 188 lb cantilever umbrella base supports 9 to 10 ft offset hanging umbrellas across backyards, gardens, and poolside decks. Each plate holds up to 27 lbs of water, 38 lbs of sand, or 47 lbs mixed, and the four plates stack into a 32 x 32 in cross footprint. Hdpe construction resists weather, Uv exposure, and surface wear, while grooved cut-out handles ease transport between sites.
