Robelle 3221-4 Pool Cover for Winter, Dura-Guard, 21 ft Above Ground Pools

The Robelle Dura-Guard Winter Pool Cover is a heavy-duty solid winter pool cover. Solid pool covers do not allow water to pass through their material. The Robelle Dura-Guard Winter Pool Cover features a heavy-duty 8 x 8 scrim. The heavy-duty polyethylene material used for this cover weighs 2.36 oz./yd2. Both the scrim count and material weight are the best indicators of the strength and durability for your pool cover. This is a heavy-duty pool cover designed to protect your pool from the winter elements. The Robelle Dura-Guard Winter Pool Cover features a green topside and a black underside. 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 Caution: Ensure the pool cover is properly secured to avoid accidental opening. Keep children and pets away from the pool cover to prevent drowning. Inspect the cover regularly for damage and replace if necessary.
