This outdoor offset patio umbrella with cantilever and crank will add the perfect shaded space to any patio, deck, yard, or garden. This umbrella is perfect for hanging over outdoor dining tables, hammocks, deep seating patio furniture sets, and more. Each umbrella has a durable steel pole and 8 steel ribs for extra strength and durability against the elements. The 2 twist knobs on the umbrella pole may be loosened allowing the center of the umbrella to rotate so the umbrella base does not have to be moved once it has been set in its desired location. The umbrella is made from 100% polyester for extra durability and comfort. The base can be easily weighed down with four 30 lbs paving stones or concrete weights (not included). Heavy-duty water/sand umbrella bases may also be purchased separately. Easily open, tilt, fold up, and store this umbrella! Make sure to fold and tie back in harsh weather conditions for extra longevity. Addtional Details: The digital images we display have the most accurate color possible.
