I bought this to be used with my new Arlmont Hawaa cantilever 10’ umbrella. Because the umbrella is so sturdy and well constructed, it really needs a heavy duty base. This one does the trick because it can be weighted down by filling with sand or water (I used water). You’ll need this seriously strong base on a breezy day. It’s perfect and specifically designed to be used with the Arlmont cantilever.
