A simple yet highly effective way to keep your above ground pool cover in place all winter is by attaching wall bags to the cover. Wall bags are used to hold down the cover thereby protecting it from wind damage. They're made out of heavy gauge vinyl and can easily be filled with water from a garden hose. The bags lie on top of your cover around the inside perimeter of the pool, it is recommended to use a wall bag every 2-3 feet. They have grommets at the top that allow you to attach them to your cover's cable. For more information feel free to contact the pros at PoguePoolSpa.com!
