Using your 11-foot dark gray cantilever patio umbrella is a piece of cake. Just use the easy-to-operate hand crank to open and close it. You can adjust the pole to different angles to block the sun effectively. The side-post design gives you plenty of space to move around under the umbrella. When not in use, it's easy to store and transport. Remember, although it comes with a cross stand, an additional weighted base is recommended for better stability, especially in windy conditions. This umbrella is made of durable aluminum ribs and a polyester canopy that can withstand most weather conditions. But to keep it in top shape, try to avoid leaving it out in extreme weather for long periods. If it gets dirty, you can gently clean the canopy with mild soap and water. With proper care, your umbrella will serve you well for many outdoor seasons.
