Anchor the shade exactly where you want it with this fillable patio umbrella base that sits ready for sand or water and supports poles up to 1.5 inches across. A built-in carry handle makes it easy to roll the empty base across the patio, then top off the reservoir to lock the umbrella in place against summer breezes. The matte black finish blends into most outdoor decor and the wide footprint stays planted on decks, pavers, or turf.
