Cantilever patio umbrellas must be securely installed to prevent accidents. That means using a base or a more permanent installation. This kit lets you install your umbrella securely in the ground. Designed for the Fiji and Bali cantilever umbrellas, it's a great alternative to an above-ground base or weights. You’ll need to set it in cement when installing. Note: the canopy clearance will be 7.5 inches lower.
