Six canopy weight plates stabilize patio umbrella bases, tents, canopies, and similar outdoor structures by wrapping around legs up to 1.25 in wide so added weight sits close to the ground. Each 9.5 x 9.5 x 2.75 in plate is made from weather-resistant PE and can be filled with water or sand, increasing versatility for different sites. A no-pinch opening helps you slide the plate into place without squeezing fingers. Male and female connections let you stack plates securely, and the included strap keeps the six plates bundled for transport and storage.
