Stylish, Reliable & Weather-Resistant Outdoor Umbrella
Elevate your outdoor lounging experience with the Shademaker Aquarius 7.5’ Square Centerpost Umbrella! This weather-resistant umbrella features a commercial-grade center pole made from hard-wearing, powder-coated aluminum so that you can enjoy a durable and reliable shade for years to come. For longer-lasting performance, the framework of the canopy is powered by heavy-duty nylon hubs, metal fasteners, and fiberglass ribs.
Available in a variety of contemporary colors and neutral tones, Aquarius is made from 100% solution-dyed acrylic and polyester fabric, woven by two of the most popular names in outdoor fabrics: Sunbrella® and O'Bravia®. These premium materials offer superior resistance to UV rays, mildew, fading, wear, and tear, making this umbrella perfect for any commercial, market, or residential space.
Also available in 7.5' Octagon and 9' Octagon models.
Why Choose the Aquarius 7.5' Square Centerpost Umbrella
