Overview
This is the metal band clamp that locks the lid to the tank on Waterway Crystal Water pool filters. Replace it if the clamp is bent, rusted, cracked or will not hold the lid tight, which can cause leaks or a dangerous lid separation under pressure. It is the current-style 3-segment clamp, which Waterway uses on both the cartridge and DE Crystal Water models.
