This tray clamps onto an existing umbrella pole and turns the space around it into a surface for drinks, fruit or a phone, which is useful on a patio with no side table. Three adapters fit poles of 1.5", 1.34" and 1.26", and the tray distributes load evenly so the pole is not bent by the weight placed on it. Premium ABS handles sun and rain, and the simple structure assembles without tools. Measures 23" across and 8" tall at 4 lbs, light enough to move with the umbrella.
