It is not a plate setter( BGE ). I have an Akorn and what you see is a 15" x 2" deep cake pan with 1" of sand in it. I cover the pan with foil down against the sand. I have tried many different types of heat defusers including ceramics. This is what I came up with a couple years ago and am quite satisfied with it. It catches the dripping from the meat and clean up is easy. Just toss the foil and re-foil for the next cook. I also don't have to worry about flare ups when I am doing chicken at 375*. The pan catches all the drippings rather than going into the coals and causing flare ups when I open the lid. For 400* to 800* cooking, I take the pan out. Just works great for me. I get less of a smoke ring than I do when cooking on my two offsets, but that does not bother me.
