Winter Covers The Winter Debris Cover is tailored for your pool, making it an excellent barrier against leaves and debris whilst allowing rain water through – therefore preventing dirty water build up on top of the cover. The cover is easy to fit, abrasion resistant and, being manufactured from the best quality material available, is proven to be both reliable and effective. It is available with a choice of tension fittings and anchors and can also be supplied as a Super Deluxe model, reinforced with criss-cross straps across the entire cover.
