Pool Skimmer sock: Pool Skimmer reusable socks are super stretchy and super soft to the touch. They have good elasticity and stretch quite easily to cover the skimmer basket, making them perfect for use in the pool. Perfect Filtration: Pool Skimmer Socks work with most pool skimmer baskets. The Pool Skimmer Sock captures leaves, grass, hair, oil, pine needles, pollen, insects and other debris that can clog your pool filtration system. Stretchy fabric fits perfectly in your basket. Wide Compatibility: Our Pool Skimmer socks are made of thick superfine nylon fabric (dimensions: 20.5 x 13.5cm / 8.07 x 5.31inch), high quality, durable, highly stretchable, easy to stretch, suitable for most types of swimming pool pumps, filter baskets, swimming pool baskets or filter baskets, etc. All you have to do is slip them into the separator basket, put them back in the basket and change your pool socks regularly. Easy to use and reusable: Sets up in seconds, just slide the Pool Skimmer Socks over the basket to catch debris in the water. A large part has been filtered (also half of a small pond), which relieves the sand filter, so cleaning/rinsing has to be done less often. Note: After 4-8 weeks, you can discard them and replace them with a new reusable separator filter, or wash them and continue to use them.
