Our 4-piece weight plate set will fix your tent, pop up canopy or patio umbrella without being blown over! Made of high-quality PE, our weight plates have good weather resistance, which can prevent fading and aging caused by sun and rain. The no-pinch design enables easy and safe installation without hurting fingers. What' more, each weight plate has an injection spout that allows you to fill in water or sand to increase weight to better hold down the canopy. Compared with the bulky concrete bases and unsightly sandbags, our weight plates provide a more stylish look while ensuring excellent stability.
