This Avantco 17813920N lid cover is a perfect replacement for the one that came with select CPW-47-HC and CPSS-47-HC series units. This part is the hinged plastic cover on the operator's side of CPW-47-HC and CPSS-47-HC dipping cabinets - it swings up and behind the sneeze guard when you need to serve customers, and when you aren't using the cabinet this cover should be closed to help minimize temperature loss and reduce the strain on your refrigeration system. By doing this you also keep your product at the right temperature for serving and prevent outside contaminants from entering the cabinet.
