The Auto Tilt 9' Round Aluminum Replacement Frame is designed to make your life easier, allowing you to effortlessly engage the tilt by turning the crank clockwise. Two poles are held together with a convenient push button coupling, ensuring maximum stability and durability. Constructed with a powder-coated aluminum frame and a steel cable lift, this umbrella is built to last. In addition, the fiberglass ribs are engineered to bend and flex in windy conditions, providing added durability and protection from the elements. Galtech recommends a 75 lb. minimum base for all free standing application. A 40 lb. base is sufficient for table mounted umbrellas. This style is ideal for up to 54" tables.
