The Shademaker Sirius 11'5" Octagon Commercial Umbrella combined practical functionality, durability, and an elegant look that will see it fitting into any commercial or residential setting. Whether you're designing a comfortable brunch setup on your restaurant patio, or creating a poolside retreat, this cantilever umbrella will provide you with the cooling shade that you're looking for. The durability in design will ensure that the umbrella can stand up to daily use, while also standing strong against the elements it will face year-round. The O'Bravia and Sunbrella fabric choices offer a wide variety from which to select your favorite colors. Whether looking for something understated or something a bit more daring, you'll find that there is a color choice that's just right for you. The easy to operate crank lift system and the removable crank handle ensure that you can open and close the umbrella without issue. The included protective cover will help to keep your umbrella protected from the elements, as well as help to keep it clean.
