Hayward TOPCLOSURE PLATE-C3020/4020

The Hayward Top Closure Plate for the C3020 and C4020 series is a heavy-duty structural manifold component designed to align and secure multiple cartridge elements within the SwimClear multi-element filter tank. Manufactured from a high-strength, glass-reinforced thermoplastic, this plate is engineered to withstand the continuous hydraulic pressure and chemical exposure typical of a high-capacity pool filtration system. Its primary function is to seat firmly atop the internal filter cartridges, ensuring they remain perfectly centered and stabilized so that water is forced evenly through the filtration media without bypassing the elements. The plate features a series of molded recessed sections to accommodate the cartridge end caps and often includes a centralized port for the air relief assembly to pass through, maintaining the internal plumbing's integrity. For shipping and logistical purposes, the estimated weight of the Hayward C3020/4020 Top Closure Plate is approximately 4.2 pounds in its retail packaging, while the actual weight of the molded plate itself is roughly 3.5 pounds.
