Actually I can get a pair of KC style ribs side by side in a pan but I first put down paper towel, the raised grate would work too. Then wax paper or something to keep the film from "gluing" themselves together for the next layer of ribs! So in a 4" deep full size pan I can get 4 racks easily. I don't have an raised grates...not sure what you mean. I keep the heat to a minimum because they were hot out of the oven and will cool very slowly to 140. But then they will live in the refrigerator until sold.
