The Hose Reel Covers are made with UV protected materials to add an increased layer of protection for any Hose Reel's that may be positioned directly in the sun at any given length of time. They also protect the Hose Reel from any creatures that may find their way into the reel through the screw holes. Please keep in mind the cover is fabric and will eventually deteriorate from the elements, however it is a great value way to protect your investment over time.
