Made from high-quality teak wood, the Galtech Rotational Tilt 9' Round Teak Replacement Frame is both stylish and durable, ensuring that it will last for years to come. One of the standout features is its Rotational Tilt functionality, which allows you to easily adjust the angle of the umbrella to block the sun no matter where it is in the sky. Additionally, the umbrella features a Crank Lift mechanism with a steel cable, making it incredibly easy to open and close the umbrella as needed. The Push Button Coupling is another great feature of this umbrella, providing added stability and ensuring that the umbrella stays securely in place even on windy days. And with the tilt engaged by simply rotating any rib clockwise, it's easy to adjust the angle of the umbrella to your desired position. Umbrella base is sold separately. Galtech recommends a 75 lb. minimum base for all free standing application. A 40 lb. base is sufficient for table mounted umbrellas.
