Heavyweight for Peace of Mind: Some umbrellas need more stabilizing weight than others. That's why we allowed our offset patio umbrella base weights can be filled with either water or a water/sand mixture to best need your family's needs. Filled with a water/sand mix, the max capacity is 220 lbs total (55 lbs per section). Filled with water, the max weight capacity is 148 lbs (37 lbs per section).Set It and Forget It: We designed each cantilever umbrella base weight to accept either water or sand and placed them on the side of each section. This makes our cantilever umbrella base not only easy to fill but super easy to drain if you end up needing to move it.Fits Your Current or New Cantilever Umbrella: While our offset umbrella weight works perfectly with Outsunny patio umbrellas, our design is universal when used with any cross-base cantilever patio umbrella. Simply fill up each section and start enjoying your shade outdoors.Easy to Move, Easy to Store: Sometimes, you just need to move patio furniture around. With carrying handles directly built into each wedge, our umbrella stand outdoor base are easy to move while storing or simply while carrying to a new location.Outdoor Umbrella Base Weights Dimension: Overall Dimensions: 39.25" L x 39.25" W x 4.25" H.
