Gladon Winter Cover Wrap™ is a specially formulated blue stretch film that is designed to wrap tightly around the top of an above ground pool to help secure the winter cover and protect it from wind damage. In addition to helping secure the cover, the cover wrap seals the pool to keep out dirt and help keep it clean. The film holds tight, but is easy to remove in the spring. It sticks to itself, not to your pool and cover. The film is wound on a unique core that has EZ Grip™ handles. The handles make wrapping your pool easy. The generous 500 foot X 15 inch roll permits multiple layer wrapping that creates a really tight seal.
