Sirius Sidepost Umbrella from Shademaker

As low as $2,163.00

This stylish cantilever umbrella has a sturdy aluminum frame with a silver finish and an adjustable canopy that is covered with high-performance synthetic fabric in multiple colors.

This dynamic offset umbrella has an innovative design and contemporary style. Its tall sidepost has a wide oval shape and is crafted from premium aluminum with an anodized silver finish. The process protects the metal from corrosion and exposure to the elements. Its mast also has a galvanized steel internal stem to provide additional strength and stability. The canopy is opened by a simple stainless steel crank lift system located three feet from the bottom.

This outdoor umbrella is extremely flexible and can adapt to changing sun positions or your personal preferences with ease. The square or octagonal canopy features three vertical tilt positions, eight 45° locking rotation positions and the whole umbrella can rotate 360°. It also has a built-in light adapter for adding a variety of outdoor lighting products. The single vent canopy comes in three sizes and is covered by your choice of synthetic textile from Sunbrella®, O'Bravia® and Outdura®. These premier outdoor fabric brands offer a variety of solution-dyed acrylic and polyester fabrics in multiple color and hues that are colorfast, weather-resistant and durable. When the cantilever umbrella is not in use, just fold the canopy to the mast and wrap it with the included protective cover.

Shademaker recommends securing the Sirius umbrella with a concrete or in-ground mount kit, but there is also a freestanding base. This steel base is really more of a frame in which you add stone pavers or weights that you can purchase from your local home improvement store. Depending on the size of the canopy, you will need 350-450 pounds to ensure that the umbrella is stable and can withstand windy conditions.

The Sirius offset umbrella is the perfect solution for spas, decks, residential pools and patios. It's also great for commercial settings where its shade flexibility can accommodate a variety of layouts or events.
