Add shade and style to your porch, patio or poolside area with this Dark Bronze Round Outdoor Umbrella Base. Weighing 32.4 pounds and crafted from Polystone material, this sturdy patio umbrella stand is made to endure all weather conditions without rusting, fading or cracking. The durable material is also UV-, abrasion- and chemical-resistant. Inside the decorative base, you'll find a steel tube that is powder coated to resist rust and has two exterior tension knobs on the stem that can be adjusted to precisely fit your market umbrella pole. The decorative base's circular shape provides stable support for round, square or octagonal market umbrellas with canopies up to 9 feet across. An interwoven pattern of embossed strips crisscross the 18.9-inch diameter Polystone surface to create a classic design. This weighted patio stand also includes a standard plastic adapter that can accommodate both 38mm (1.5-inch) and 48mm (1.89-inch) diameter poles. Caring for your new umbrella base is easy - just hose off and wipe clean to keep it looking like new.
