This freestanding umbrella base lets you enjoy the outdoors in the shade. It’s made of ABS plastic and features four 50.8cm square plates with rounded corners, each with a metal handle for easy positioning. This base holds up to 15kg of water or 22.7kg of sand to weigh down your umbrella, fillable via an easy-to-use spout on each plate. We love that this base works well with most cantilever cross-brace umbrella stands, making it easy to install. A cross-brace stand and umbrella pole are not included.
