ClearDeck CD1061-20 20' Wide Below Deck Inground Solar Blanket Reel. A well-maintained swimming pool provides years of enjoyment and lasting memories. As a pool owner, you can save significantly on pool heating and retention costs through regular use of a solar blanket. But a conventional above-deck solar blanket roller presents a challenge for easy one-person operation and detracts from the overall beauty of your backyard. However, with a ClearDeck® In-Ground Solar Blanket Roller, the blanket is concealed below deck and completely hidden out of sight when not in use. As a result, your deck will be less cluttered, allowing you to enjoy the beauty of your pool and landscaping as you envisioned.
