If the top lid on your Avantco DFC20-HCL ice cream freezer becomes cracked or damaged, replace it promptly with this Avantco 36031080 glass top lid! The glass lid on your unit locks in cold air and allows your freezer to run at maximum efficiency while providing a clear view of the contents. It's important to be sure that the lid closes snugly and to replace it if this is an issue. Broken glass on a lid is also a safety hazard for you and your customers.
