Our liners will fit Kayak® and Fanta Sea® rectangular on-ground pools. We offer two grades of liners to fit these pools: A Standard 20-ga. virgin vinyl liner that is backed by a 15-Year Warranty, and a Deluxe heavy-duty, full 25-ga. virgin vinyl liner that comes with a 25-Year Warranty. Both liners are U.V. protected and are of the highest quality you can buy at these prices. Protect your pool by installing a top quality liner this season.
