The 20' x 40' Gray Royal Mesh Safety Cover is engineered for superior protection and durability, offering twice the water flow of standard mesh covers while providing 90% shade. Designed to withstand heavy rainfall and snow loads, this cover features a robust "Basket Weave" construction that prevents rips and holes from expanding, and the center end step allows for a more customized fit. The gray color effectively blocks sunlight, reducing algae growth, and the heavy-duty webbing and Tension-Tech springs ensure a secure, tight fit.
