New Upgraded DEX2421JKIT Filter Tank Clamp for Hayward Swim-Clear & Pro-Grid. Secure your pool filtration system with this 2025 Upgraded DEX2421JKIT Tension Control Clamp Kit. Designed as a direct replacement for Hayward Swim-Clear and Pro-Grid filters, this clamp ensures the filter tank remains tightly sealed under high pressure. THIS IS NOT AN OEM HAYWARD TENSION CONTROL CLAMP. THIS IS A NEW/ UNUSED UPGRADED DIRECT FIT REPLACEMENT to the Hayward. Unlike older composite or plastic clamps that may crack, this upgraded version is constructed from High-Quality Aluminum. It is lightweight yet incredibly strong, providing a secure seal to prevent water leaks or dangerous air trapping. As shown in the photos. The photos provided are of the actual item you will receive! Compatible Model: SwimClear C2030, SwimClear C3030, SwimClear C4030, SwimClear C5030, SwimClear C7030, Pro-Grid DE2420, Pro-Grid DE3620, Pro-Grid DE4820, Pro-Grid DE6020, Pro-Grid DE7220. Included in the Kit. Tension Control Clamp (Metal Band). Nut & Bolt Hardware. Note: This clamp fits both the “Grid” style elements (Pro-Grid) and the “Cluster” style cartridges (Swim-Clear). ? PRO TIP FOR INSTALLATION: Apply a generous amount of silicone lubricant (like Magic Lube) to the threads of the brass tension bolt. This prevents the brass nut from stripping under tension and makes it much easier to remove when you need to clean your filter cartridges or grids next season. Upgraded Materials: Manufactured with high-quality aluminum for long-lasting performance and resistance to cracking. Complete Seal: Holds the top and bottom of the filter tank tightly in place, preventing water leakage and air pressure buildup. Perfect Fit: Engineered to match the filter housing dimensions perfectly for a seamless installation. Easy Maintenance: The tension knob design allows for easy tightening and future removal during filter cleaning cycles. Aluminum & Brass Hardware. Compatible with the following Hayward Filter Models. Hayward Swim-Clear Cartridge Filters. Hayward Pro-Grid DE Filters (Manufactured after 2007). International Buyers Welcome! (Please see note below). International Buyers – Please Note.
