The portable Island Umbrella lanai 9-ft half umbrella is the perfect solution for a tight space. It works great on a narrow deck or a balcony up against a wall, window or sliding door where a full umbrella just won’t fit. This unique shade solution requires no attachment to wall or vertical surface. Although its shade capacity is half of a 9-ft octagonal umbrella, it’s still packed with quality features at a very affordable price. The durable construction, appealing profile, and unique crank and open system ensure ease of use and long lasting durability. Enjoy a relaxing time under shade, all day long, even in tight spaces! 1 year polyester canopy warranty, 3 year warranty on pole and umbrella structure
