GLI 4' X 4' Blue Air Pillow, 500404AP
These pillows are used on above ground pools to raise the cover up, so that water will run off. Vinyl pillow absorbs freezing water’s pressure and helps protect your pool walls. They will help keep the water clear and clean until you are ready to open the pool in the springtime. They also keep off water that (when it turns to ice) will add pressure and can hurt your pool’s wall structure. Relieve your pool walls of water expansion stress! Made of heavy-duty 20 gauge vinyl, these multi-purpose pillows also help reduce the build-up of rain, leaves or snow on your winter cover. Installation is easy! It is important to note that when inflating the air pillows, the manufacturer does not recommend the pillows be filled to capacity. Follow manufacturer’s recommended fill percentage and instructions.
