Built for offset and cantilever umbrellas up to 10 by 10 ft, this weighted base replaces the usual four loose weight plates with one molded HDPE shell and a 22-in metal cross bracket. Fill it through the wide inlet with 100 lb of water, 132 lb of sand, or 176 lb of both, then open the side drain when the season ends. Two cut-out handles let the empty 11.5-lb shell travel in a single trip, and molded grooves underneath stop it creeping on smooth decking. A low 5-in profile slides under a cantilever frame without catching a foot.
