Has anyone seen a small cooking grate, probably about 15" in diam that sits on top of a WSM 18" top grate? It had collapsible legs, and is about 4" high. Essentially, it would allow 2 spares/BB's to lie flat on the 18" grate, and then a third rack on top of them laying on this 15" grate. I saw this at the Wildomar comp, and forgot to ask where they got it from.
Is that confusing enough of a description? Thx!
