SpaChoice Crystal Blue 1224S-8 BOX-CB Solar Cover, 2. Oval-12 x 24 ft. Pool

The Heavy-Duty Solar Cover is made of heavy-duty polyethylene material that retains heat. Solar covers float "bubble side down" on the surface of your pool water when the pool is not in use, trapping solar energy and retaining heat. Safety Warning Always secure the solar cover when not in use to prevent drowning hazards. Be cautious when handling the heavy-duty cover to avoid injury. Keep the cover clean and free of debris to maintain its effectiveness and longevity. Store the cover in a dry, shaded area when not in use to protect it from weather and sunlight exposure.
