Midwest Canvas - 21' Round Winter Pool Cover, 16 Year Warranty, Silver

The Midwest Canvas Round Above Ground Winter Cover with 16-Year Warranty will keep your pool clean and protected against the toughest winter storms. There will be no surprises when opening your pool next spring; only clean, algae-free water.

The Midwest Canvas 16-Year Winter Cover utilizes a thick, heavy-duty construction to prevent storm debris from tearing the material and entering your pool. This cover was built to last storm after storm, and year after year.

Each round winter cover includes a winch and cable to create a tight seal around your above ground pool. These covers also include metallic grommets around the perimeter of the material to attach optional water bags (sold separately). We also recommend applying an air pillow (sold separately) under the center of your winter cover to help push water and snow melt to the edges of your pool. Swimming pool air pillows also help absorb the pressure and weight from precipitation.
