Resin and steel construction creates a durable patio umbrella base that resists water and rust for long-term outdoor use. The 18 x 13 in base and 22-lb weight help keep a compatible umbrella steady on patios, poolside areas, gardens, backyards, or hotel settings. A 10-in support tube centers the umbrella pole and is sized for 1.5 or 1.9 in diameter poles, giving you flexibility to pair it with different umbrellas. An adjustable side handle lets you tighten or loosen the pole quickly so you can secure the umbrella or remove it for storage as needed.
