Perfect Partner for Your Patio Umbrella! Our fillable patio cantilever umbrella base stand comes with 4 plates, which can perfectly fit cross bases (not included) of your offset hanging umbrellas. When filled with water, the base can reach a weight of up to 58 kg, while sand can make it up to 76 kg. For maximum stability, a combination of water and sand can increase the weight capacity to an impressive 94 kg. Besides, it is made of premium HDPE material, which can resist all weather, ensuring long-lasting durability. 4 plates can be stacked when not in use, therefore it would not take up much floor space for storage. And there exist grooved handles on the bottom, bringing convenience for transportation.
