Stay in the shade with the Coral Coast 11-ft. Gazebo Umbrella with Detachable Netting. This large offset umbrella is just right by the pool or spa, or on the patio. Enjoy family meals or conversation with friends under the cool shade of this Coral Coast Offset Umbrella. For additional shade, add this umbrella to larger outdoor conversation or dining tables that don't accommodate umbrellas or have hard-to-reach umbrella holes. A sturdy steel pole is finished in a nice, neutral bronze color and topped off with a spun-polyester cover in a variety of complementing colors. The canopy conveniently opens and closes by using a crank-lift system. This grandly scaled umbrella can provide shade for a large dining table or conversation set. Please take into consideration that this umbrella does not rotate. The offset umbrella also comes with pest control netting. Simply zip the netting to the zipper hidden under the valance for complete protection. The pest control netting also features a convenient door zipper for easy access in and out of the setting. Please note that the concrete blocks to weigh the base down are not included with this umbrella; we recommend that each concrete block weigh at least 50 pounds and measures 18 x 18 inches. We recommend a total minimum weight of 200 lbs., more for windier areas. Paving stones or other blocks for this purpose can be purchased at most hardware or garden stores. The four legs on this base are not removable. The pole diameter is 2 inches and the base measures 39.5 inches by 39.5 inches. Value-priced, this umbrella comes with a 6-month warranty. The umbrella base is positioned at a slight angle - 88 degrees on the backside - to allow for proper weight distribution when the umbrella is opened.
