I received them free with my smoker, which is funny because it's not even really possible to hang ribs in a #1. ;D ;D Needless to say I have never used them. No one else here uses them as far as I know. I see no real advantage to hanging ribs. It is supposed to be more efficient for space, but I don't think it is. Ribs smoke great bone side down, flat on a rack. If you want to get more ribs in, you are better off purchasing the optional side rail assembly that adds more shelves, and purchase some extra racks. I'm still trying to come up with some other use for for my rib hooks.
