Product Description The Robelle Ultra Winter Pool Cover is a commercial-grade solid winter pool cover. Solid pool covers do not allow water to pass through their material. The Robelle Ultra Winter Pool Cover features a commercial-grade 14 x 12 scrim. The commercial-grade polyethylene material used for this cover weighs 4.5 oz./yd2. Both the scrim count and material weight are the best indicators of the strength and durability for your pool cover. A cover with a high scrim count and heavy material, like the Robelle Ultra Winter Pool Cover, will last longer than other covers. This is a commercial-grade pool cover designed to protect your pool from harsh winter elements. The Robelle Ultra Winter Pool Cover features a dove gray topside and a black underside. This pool cover includes a perimeter binding. 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 Always ensure the pool cover is securely fastened to prevent accidental removal, which could lead to drowning hazards. Keep the pool area clear of debris and never allow children or pets to play on the cover. Store the cover in a dry place when not in use to prevent damage from weather or sunlight exposure.
