Filled to its 348 lb maximum with water and sand, this cross base still moves: four rolling wheels and two cut-out handles let one person reposition it. Two large filling spouts speed the job, and capacities run to 220 lbs of water or 310 lbs of sand on their own. The 33" x 33" cross spans a 34" square footprint at 8" tall and suits cantilever umbrellas from 8 to 10 ft. HDPE resists fading and cracking outdoors. Empty weight 31 lbs; base and manual included.
