The Robelle Blue Mesh Winter Pool Cover is a heavy-duty mesh winter pool cover. Mesh pool covers allow water to pass through their material. This is a heavy-duty pool cover designed to protect your pool from the winter elements. Customers buy mesh pool covers because they require less maintenance than solid pool covers during the winter months. Mesh pool covers are also good for high wind situations as the material sits in the pool water. Pool owners that use a mesh pool cover typically will have additional work cleaning their pool in the spring before opening. The Robelle Blue Mesh Winter Pool Cover features a blue color. Please order by your pool size, as the overlap goes beyond the pool size listed. This cover includes a four-foot overlap. Please order a larger size cover if you have steps (or any other irregularity) protruding from your pool. Water tube loops are placed around the perimeter of the pool cover. Water tubes sold separately. Only water tubes should be used to install this pool cover. No other method of installation is recommended. This cover should be able to comfortably float in 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. Includes a ten year warranty.
