Four steel and PP components form a square patio umbrella base that adds 50 lbs of support to help stabilize your outdoor shade. The 24-in wide base increases ground contact area for added stability, while a powder-coated surface is water-repellent and resists rust for use in changing weather. Two adapters fit umbrella poles with 1.6-in and 1.9-in diameters, and dual tightening handles keep the pole firmly in place. Built-in wheels, a side handle, and tool-free assembly simplify setup and relocation.
