The 42" Serious Big Bad's upper grate is so large that covering it with one big baking stone made it just too heavy to lift. This inspired us to make it in two pieces. 23 lbs each! **For now, we can only supply baking stones with grill deliveries. We are going to need to make a special "after purchase/out with UPS box" for the baking stones.. Our standard boxes are not designed to be tossed around by the gorillas that obviously work for UPS. They are arriving broken as often as intact.
