Compatibility: Effortlessly works with Polaris 280 and 480 multi-purpose bags, part K13 and K16. Hook and loop fasteners are designed to fit securely into the pipe cleaner and seal tightly on the top. (Please confirm your Polaris model before purchasing) These nylon mesh pool cleaner bags with strong stitching and mesh fabric are perfect for picking up debris or collecting small leaves and twigs without tearing at the bottom of the pool. The extra zipper opening makes this pool mesh bag 3 times easier to empty and clean debris from the filter bag. Easy to Use: Our multi-purpose filter bag is easy to install, remove and clean. The upgraded clips fit perfectly on the cleaner and user, it can be installed in seconds. The Multi-Purpose Filter Bag is open on 2 sides, making it very easy to clean. This is not a genuine part, but an aftermarket part. Polaris does not create or sell parts that match or better than the original performance, it gives you a more cost-effective option.
