Outsunny 175 lb Brown Plastic Patio Umbrella Base Weights, Waterproof design (4 Count)

An umbrella stand should do just that, make your umbrella stand, but heavier models may need reinforcement. That's where our weights come in; coming in a pack of four to keep your cantilever planted, our weights are heavy when you need it and light when you don't. Unscrew the nozzles to put water or sand inside for up to 175 lbs. of protection. When not in use, handles help make them portable, and they stack for storage. Made of thick, waterproof plastic they were designed with outdoor in mind.
