{"product_id":"hayward-cx3020da-top-closure-plate-swimclear-c3020-c4020","title":"Hayward CX3020DA Top Closure Plate | SwimClear C3020\/C4020","description":"\u003cp data-start=\"261\" data-end=\"994\"\u003eThe Hayward CX3020DA Top Closure Plate is designed to secure the upper assembly of SwimClear multi-cartridge filters, specifically the C3020 and C4020 models, by locking the cartridge pack in place for proper flow and filtration. Its molded construction matches the original Hayward layout, giving the plate the rigidity and alignment needed to maintain an even seal across the manifold and cartridges. This component supports the filter’s internal structure during pressure cycling, helping the cartridges seat correctly during operation and cleaning. Replacing a worn or cracked top plate helps restore consistent water flow and keeps the filter performing the way it was originally engineered to operate.\u003c\/p\u003e\n\u003ch3 data-start=\"996\" data-end=\"1014\"\u003e\u003cstrong data-start=\"1000\" data-end=\"1014\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"1015\" data-end=\"1792\"\u003e\n\u003cli data-start=\"1015\" data-end=\"1174\"\u003e\n\u003cp data-start=\"1017\" data-end=\"1174\"\u003e\u003cstrong data-start=\"1017\" data-end=\"1048\"\u003eFits C3020 \u0026amp; C4020 Filters:\u003c\/strong\u003e Built for the SwimClear multi-cartridge design, ensuring correct alignment and secure placement over the cartridge cluster.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1175\" data-end=\"1319\"\u003e\n\u003cp data-start=\"1177\" data-end=\"1319\"\u003e\u003cstrong data-start=\"1177\" data-end=\"1209\"\u003eReinforced Molded Structure:\u003c\/strong\u003e Made to handle pressure fluctuations and cleaning cycles without warping, cracking, or shifting under load.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1320\" data-end=\"1476\"\u003e\n\u003cp data-start=\"1322\" data-end=\"1476\"\u003e\u003cstrong data-start=\"1322\" data-end=\"1345\"\u003eOEM-Style Geometry:\u003c\/strong\u003e Follows the original Hayward top-plate layout to support proper cartridge seating and stable water distribution inside the tank.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1477\" data-end=\"1633\"\u003e\n\u003cp data-start=\"1479\" data-end=\"1633\"\u003e\u003cstrong data-start=\"1479\" data-end=\"1507\"\u003eEssential for Even Flow:\u003c\/strong\u003e Helps maintain correct internal flow paths, reducing channeling and supporting consistent filtration across all cartridges.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1634\" data-end=\"1792\"\u003e\n\u003cp data-start=\"1636\" data-end=\"1792\"\u003e\u003cstrong data-start=\"1636\" data-end=\"1668\"\u003eStraightforward Replacement:\u003c\/strong\u003e Simple to install during filter service or rebuilds, restoring structural integrity without modifying the tank or manifold.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHayward SwimClear Multi-Cartridge C3020 Filter\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHayward SwimClear Multi-Cartridge C4020 Filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"2977\" data-end=\"2998\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"2999\" data-end=\"3299\"\u003eThe Hayward CX3020DA Top Closure Plate is a common replacement for technicians servicing multi-cartridge SwimClear filters.
