Sun2Solar Quick Drain Grommet Kit for Solar Heating Covers | Set of 6 | Water Drainage System Helps Remove Excess Water From Atop Blankets | Designed for In-Ground Above-Ground Swimming Pools and Spas LESS HASSLE - There is no need to struggle taking a solar cover off of the swimming pool due to the excessive water resting atop. Quick drain grommets offer a simple solution allowing water gathered on your solar blanket to exit back into the pool while trying to either roll up or take it off. ALL POOL SHAPES AND SIZES - Comes with 6 individual pieces for any size cover. The positioning of the quick drain system is dependent on pool shape and when done will help you spend more time swimming and less struggling with getting into your pool. ELIMINATE THE WEIGHT - The extra weight of water on top of the solar cover will be eliminated with the quick drain grommet set, reducing stress on both your cover and solar cover reel. HOLD YOUR COVER DOWN - As an added bonus, these grommets help anchor your cover by enabling some water to rest atop the solar blanket. This comes in hand with gusty wind conditions where the cover may billow up at times. SIMPLE INSTALLATION - The kit includes 12 individual plastic pieces used to quickly make a set of six grommets. All you will need to put these together is a hard and flat surface, a small hammer and the solar cover.
