The Trufrost Drop-In Frost Tops are specially designed to efficiently hold fast moving, pre-chilled food products such as grab & go menu items, trays of appetizers and cold beverages at optimum serving temperature and provide an easy, self-serve access. The display surface fits flush with the countertop to limit the effect of ambient temperature on the display area and to help maintain a pleasing, full frost view. For best performance, stainless steel pans are recommended for placement on the Frost Top.
