This Sunbrella outdoor patio market umbrella is perfect for any outdoor patio or backyard space, at festivals, or at the cabin/camper. It is designed for use as a freestanding umbrella over a patio sofa set (base not included) or with an outdoor dining table (ranging from 42" - 54"). The patio umbrella is engineered to last with a 103" diameter canopy made from 100% solution-dyed 220g acrylic Sunbrella fabric. Solution-dyed means that the fibers the fabric is made from are dyed before being woven which results in a more long-lasting, fade and stain resistant color. The 2000-hour color fastness means that this fabric will not fade as quickly as others. The pole and ribs are made from rust resistant powder-coated aluminum while the fittings are stainless steel. The umbrella''s 1.5" diameter pole means that it can fit most standard-size bases. The pole is steel with an attractive speckled bronze powder coating. To use the auto-tilting option simply open the umbrella all the way and keep cranking it until the desired tilt angle is reached.
