Resenkos Outdoor Umbrella Base, 18 Inch Fillable Heavy-Duty Round Umbrella Base Stand, Black

<p>This ultra-stable 18-inch round umbrella base stand is engineered for maximum wind resistance and long-term durability. Its large dual-fill reservoir accepts either sand (up to 55 lbs) or water (up to 4 gallons), delivering up to 66 lbs of total ballast when combined — ideal for securing 9–10 ft market umbrellas in residential patios, gardens, cafes, and commercial outdoor spaces. Crafted from high-density polyethylene (HDPE) with reinforced metal components, the base resists UV degradation, cracking, rust, and weathering — ensuring reliable performance season after season. A built-in ergonomic handle and lightweight 4.5 lb empty weight make transport and repositioning effortless, while non-slip protective pads on the bottom prevent surface scratches and enhance grip on decks, pavers, and concrete. The base includes two universal plastic pole inserts compatible with standard 1.5-inch and 1.9-inch umbrella poles, plus a convenient hand-turn tightening knob for quick, tool-free installation and secure locking.</p>
