The Shademaker Sirius 11'5 octagon crank lift offset patio umbrella features a nautical influence with stainless steel hardware and superior aluminum alloy for durability that lasts. Sirius umbrellas are built to withstand torrential rains and windstorms with heavy duty masts and massive rib wall thickness, as well as comprehensive high-performance and commercial grade fabric options. These umbrellas also feature industrial strength hubs and fittings that ensure the umbrella’s tilt system is reliable and simple to use. 

Unlike the the Shademaker Libra and Astral patio umbrella models with center post masts, the Sirius utilizes an oval side post mast with an innovative 360 degree tilt system that follows the summer shade as the sun moves across the sky. Sirius’ variability makes it an excellent summer shade solution for residential or commercial pools, spas, patios and decks. Cool-Off.com Shademaker Sirius umbrellas provide even greater flexibility and convenience with concrete, wood deck or in-ground mounting options and free shipping.
