These pool covers are designed for the round, above-the-ground swimming pools. They will keep your pool free of dirt insects and debris when it is not in use. Made of polyethylene, the pool cover weighs 90 g/sqm, which is tear-resistant and water-repellent. Thanks to the small drain holes in the middle, the pool cover allows rain water to go through instead of accumulating on top. The small drain holes also create ventilation. The quality stitching on the edge of the cover ensures its years of service! The cover can be fixed to the pool by pulling the rope and fastening the cover, very easy to use!
