Anchored by 50 lbs of solid steel, this 24-inch square umbrella base delivers dependable stability for market and cantilever umbrellas. The powder-coated surface resists rust and Uv fading, preserving a clean appearance through years of outdoor exposure. Two built-in wheels let you reposition the base with the umbrella still attached, and dual adapter rings accommodate 1.6 in and 1.9 in pole diameters.
