Product Description The Pool Mate Sandstone Winter Pool Cover will protect your pool from winter elements. This is a solid winter pool cover that will not allow water to pass through its material. The Pool Mate Sandstone Winter Pool Covers is constructed of extra heavy-duty polyethylene. All seams are heat sealed for better performance. The sandstone topside of this pool cover is coated to prevent UV damage. Please order by your pool size, as the overlap goes beyond the pool size listed. This cover includes a four-foot overlap. If you have a very large top rail, please consider a larger pool size. This cover should be able to comfortably float on the pool water without excessive stress. This cover is not meant to be used as a debris cover during the swimming season. This winter pool cover is intended to be used during the off-season. This cover is meant for traditional above ground pools with a traditional top rail. Includes a winch and cable that should be used to secure your pool cover through the grommets around the perimeter of the pool cover. For extra securing, cover clips and cover wrap (both sold separately) are suggested for pool closing. No other method of installation is recommended.. Safety Warning This product includes general safety warnings about potential drowning hazards, entrapment, and suffocation risks associated with above-ground pool covers. Users should exercise caution when handling the cover material, installing the cover, and securing it in place using the winch and cable. It is recommended to use cover clips and cover wrap for extra securing during pool closing. Always follow the manufacturer's instructions for proper installation, use, maintenance, and storage. Protect the cover from excessive stress, weather, and sunlight exposure.
