About this Item Sturdy Construction: The 240G poly umbrella canopy is fade resistant and provides 95 square feet of coverage. The umbrella frame is constructed from aluminum which has a Bronze powder coat paint finish for the maximum weather resistance. Aluminum is prefered for outdoor use as it won't rust and is highly resistant to corrosion. Large Cantilever With Double Wind Vent: The 11' round offset umbrella canopy provides coverage for larger patio or decks, and has a double wind vent at the top to allow hot air to escape and cool breezes to blow through. This size is most popular to cover outdoor conversation sets or larger patio dining sets. 360°Rotation, Lift and Tilt Design: Turn the crank handle to open and close the umbrella. To engage 360° rotation, use the foot pedal on the main umbrella pole and turn the frame to the desired position. There are 6 tilt positions that can be accessed with the lever on the umbrella pole. Comes with Same-color Protective Cover: To prolong the life of this offset umbrella, please don't leave it open when it's windy or not in use. The canopy is easily closed with the crank handle, and there are ties to secure the canopy to the frame as well as a protective cover to help keep the canopy protected when not in use. To clean the canopy, hose off and allow to air dry. Cross Base Frame: The X shaped umbrella base requires a minimum of 176 lbs of base weights (not included). Base weights can be purchased at LAUREL CANYON brand store, and additional weights can be added for more stability.
