It is designed for Zodiac s Versa Plumb® system to easily connect with the rest of your Zodiac equipment while using minimal space on the equipment pad. The CS filter features easy grip ergonomic handles and extra large drain ports in a small, compact thermoplastic body. The CS filters are technologically advanced and filled with many user-friendly features.
