The Pool Mate Econo-Mesh Oval Above Ground Winter Swimming Pool Cover doesn't mesh around. This durable cover requires less maintenance than solid pool covers and is perfect for areas with high-precipitation because it prevents water and debris from collecting on top. Reinforced binding around the edges prevents premature wear and tear, and solid grommets placed every four feet around the perimeter ensure a tight and secure fit all winter long. Use the included winch and cable to attach the grommets to the pool and enjoy peace of mind while you wait for spring. Includes a 10-year warranty.
