The Treasure Garden 11' Cantilever Umbrella Base properly supports the larger cantilever umbrellas to ensure your shade stays in place while there's a slight breeze. Cantilever umbrellas are beautiful sculptures with sturdy frames that gracefully support canopies overhead, but without the proper support the majesty of the umbrella can come crashing down to completely ruin an otherwise pleasant setting. In order to prevent any disastrous distractions at your back yard party, secure your Treasure Garden AKZ Cantilever Umbrella with a sturdy base like this.
