From another topic it was mentioned that maybe a foil steam table lid might be easier than the ever so popular job of climbing in and foiling the bottom of the larger units. Indeed on Amazon the full size foil steam table lids from Web Restaurant Store are and almost perfect fit at 13.5 x 21.1 in. Meat would have to be right up against the wall to miss it. Ordered a 10 pack to try. About 0.34 ea for larger pack if they work. Will keep yall posted. 5 lbs jalapeno-soy soaked wings and a Bloomin' Bologna on now!
