Keep your cross-style offset umbrella anchored and upright with a set of these cantilever umbrella base weights. These 4-piece umbrella weights can be easily filled with water or sand to weigh down a cross-style cantilever umbrella (fill material not included). Each weight features a durable plastic construction with an easy-to-fill spout for convenient filling. Simply fill each base plate and screw the cap on tight. The plastic design is durable enough to resist the elements. Plus, you can easily dump out the fill materials when the season is over. The lightweight design makes them easy to stack and store during the off-season. The classic black color will complement any patio decor or umbrella canopy color (umbrella not included). Choose between a set of four wedge pieces that form a circular shape around the umbrella base or 4 square pieces that form a rectangular shape around the umbrella base.
