HPI's Yard Guard Pool Cover Air Pillow helps protect both in-ground and above-ground pools covers. With above-ground pools, using an air pillow relieves stress from the walls of your pool caused by ice. It also reduces the build-up of snow or rain water on your winter cover. Build-up can lead to your pool cover sinking under the pressure and tearing. To utilize the air pillow, simply inflate & place it under your pool cover. You can secure it in place using the built-in grommets. Once set up, the air pillow will help protect your pool cover all winter long. 

Key Features: 

• Absorbs pressure caused by ice expansion, protecting the swimming pool walls
• Creates a slope on the cover to force debris away from the center of the pool
• Prevents a pool cover from sinking or tearing from build-up of rain water or snow
• Made from 16-gauge vinyl
