Robelle Supreme 20 ft. x 40 ft. Rectangular Green Solid In-Ground Winter Pool Cover 372040R - The Home Depot

Protect your in-ground swimming pool with the Robelle Mesh winter pool cover. Unsealed mesh materal allows water to pass through the cover, eliminating the need for a cover pump. The polyethylene material is constructed with a 10x10 scrim (threads per square inch). Covers with a higher scrim will have a better overall quality, strength, and durability. The material weighs 3.1 ounces per square yard which is important because heavier covers will be affected less by extreme elements.
