The Shademaker Sirius 8'9" Square Commercial Umbrella holds the distinction of being one of the first designs released by Shademaker. For more than a decade this outdoor lifestyle enhancement company has continued to expand their catalog of shade solutions, while sticking with the classics that work. The Sirius offers a contemporary design that doesn't compromise on functional practicality.

There are a number of great features that the Shademaker Sirius 8'9" Square Commercial Umbrella boasts. This innovative design offers a 360-degree rotation and tilting so that you can get the cool comfort of shade just where you need it to be. The umbrella also offers eight 45-degree locking rotating positions. It's a snap to open and close this umbrella, with the easy to operate crank lift system and the removable crank handle. The built-in light adapter allows for an easy transition from afternoon sunshine to early evening twilight. You'll appreciate the options in color, with durable top-quality fabrics that have been designed to stand up to the elements. Be sure to use the included protective cover when your umbrella is not in use.
