Hayward TOP CLOSURE PLATE -C5020-

The Hayward Top Closure Plate for the C5020 series is a vital internal structural component specifically engineered for SwimClear multi-element cartridge filter systems. Fabricated from a high-impact, glass-reinforced thermoplastic, this plate is designed to sit atop the internal cartridge stack, providing the necessary downward pressure to keep the filter elements perfectly aligned and securely seated against the bottom manifold. Its primary mechanical role is to ensure a tight hydraulic seal, preventing unfiltered water from bypassing the cartridge media and leaking into the clean water return line. The plate features precision-molded recesses that correspond to the top of each filter element, along with a central opening or mounting point for the air relief tube and tie rod assembly. Built to survive the corrosive environment of chlorinated or salt-water pools, it maintains its shape and rigidity even under significant hydraulic stress and temperature fluctuations. For shipping and logistical purposes, the estimated weight of the Hayward C5020 Top Closure Plate is approximately 3.8 pounds in its retail packaging, while the actual weight of the molded plate component itself is roughly 3.2 pounds
