This food pan carrier keeps meals at serving temperature for up to 4 hours without being plugged into anything. All of the performance comes from the EPP shell itself, so the carrier works in a vehicle, on a table or anywhere else there is no outlet. Its rated range runs from -40 to 212 degrees Fahrenheit, which means the same box that holds hot dishes will just as readily keep cold ones cold. Storage is arranged in two tiers. A removable tray with 16-quart capacity sits above a 32.8-quart box, with 8 inches of shelf clearance between them, and the tray comes out entirely when full-depth space is wanted. The two-level layout allows food to be separated by course or by temperature instead of stacking everything into a single cavity, and the box interior measures 20 by 19 by 7.5 inches. The tray itself is rated to hold 33 pounds. Closing the carrier engages safety buckles, and two keys are supplied for a reliable locking system, so a lid cannot pop open in transit and contents stay secure while unattended. The top is grooved to match the bottom of another unit, which lets several carriers stack squarely rather than sliding against one another when they are moved together. That makes it practical for a party, catering run, buffet or camping trip where more than one dish has to move at once. Nothing needs assembly and nothing needs power. The complete carrier measures 23.5 by 22 by 22.5 inches and weighs 13.5 pounds empty, light enough to load and carry while still holding its temperature.
