- Use one wall bag every 2-3 feet
HOLD YOUR POOL COVER DOWN, EVEN IN HIGH WINDS! These handy wall bags help hold your pool cover down in high winds and protect it from wind whip and damage. Our bags are made of heavy-gauge vinyl and are easily filled with water using a garden hose. They are designed to lie on top of the pool cover around the inside perimeter of your pool. Rugged grommets on top of each bag allow you to fasten them to your pool cover's cable. Use one wall bag every 2-3 feet. Anchor your winter pool cover this year with wall bags!
