Anchor an outdoor umbrella against breezy afternoons using a 49 lb resin and steel base built for freestanding or table-mounted use. The hand-turn tightening knob locks the umbrella pole in place, while two included adapters fit 1.5 in and 1.9 in pole diameters for compatibility with most patio umbrellas. The build resists rust, cracks, and deformation, suiting gardens, poolsides, backyards, or market stalls.
