Dometic CFX375 Lid Assembly - Black - Part# 4450021520

The Dometic Service Parts 4450021520 helps RV owners, campers, overlanders, van builders, and mobile-service users match the right Dometic cooling product, accessory, or service part without relying on appearance alone. Match this listing by Dometic model cues and part number 4450021520 before ordering.

This product is for shoppers who know the Dometic series, capacity, color, or replacement component they need. The trade-off is important: CFX, Recon, CoolMatic, accessories, and service parts are not automatically interchangeable, so use the exact part number instead of a near-match.

Why Choose This Service Parts?

Dometic mobile-cooling products can look similar across capacities, colors, and generations, but small differences matter. This page keeps the model family, capacity cues, configuration, and exact part number visible so you can compare the right cooler, cover, basket, gasket, control, or accessory before checkout.

If your existing unit, parts diagram, label, or manual lists a different Dometic number, choose that matching product instead. For powered coolers, also confirm your storage space, power source, and single-zone or dual-zone needs before buying.
