Keep your patio umbrella securely positioned with this 25-inch square weighted umbrella base designed for common pole sizes. The base includes two plastic adapters (1.6"" and 1.9"") to help fit umbrella poles ranging from 1.6"" to 1.9"" in diameter. A manual tightening knob helps hold the pole in place, while four bottom pads help reduce slipping and support stable placement on patios, decks, and other outdoor surfaces. Made with a steel base and tube, this 42 lb umbrella stand offers a low-profile square look that pairs well with many patio styles. Setup is straightforward: attach the steel tube to the base with the included hardware, insert your umbrella pole, and tighten the knob. Overall size is 25"" x 25"" x 14"", and the package includes the base and a user manual.
