The Shademaker Galaxy 11'5" Square Commercial Umbrella is one of the largest sidepost-styled outdoor umbrellas that you will find. This patio umbrella offers 131 sq. ft. of cooling shade coverage, where you need it. Whether you're setting up the perfect poolside brunch spot or looking to create an outdoor relaxation zone for your guests, you'll appreciate all of the features that this jumbo-sized umbrella can offer.

One of the important things to note about the Shademaker Galaxy 11'5" Square Commercial Umbrella is that it is recommended that you hire a licensed contractor to assist with the installation process. This not only ensures that you have the manpower needed to do the heavy lifting, but also ensures that each of the spacer buttons is installed correctly. It's a breeze to open and close this cantilever umbrella, by using the crank on the side of the post. Each part of this umbrella has been designed with durability and high performance in mind. The O'Bravia and Sunbrella fabric options are top quality and are offered in some great color choices so that you can get just the right look. Enjoy the added protection offered by the included protective cover that can help to keep your umbrella clean when not in use.

Please note: Due to the size of the umbrella, an In-Ground Post Mount Kit is highly recommended for securing the umbrella in place.
