I use the hanging rack quite often. It takes the WSM to the next level IMHO. I hang meats on it with high heat PBC style and go low n slow for bacon, sausage, and jerky.
Sausage recipes usually call for something like a 130*F for a couple hours then increase the heat to 165*F until 152*F internal. So for low n slow, I build a dual row “C” shaped fire and increased the charcoal half way thru to a stacked dual row to increase the heat and used the
expandable cooking rack for this cook.
Here's another cook - Kielbasa in the back, Summer Sausage, Can Bacon, and Cotto Salami next, then the jerky up front:
...and some bacon
Here's a high heat cook before I got the hanging hooks seen above:
I cooked it in the 22" WSM over a bed of coals of one full large chimney of lit over a half ring of unlit with the cooking grates and water pan removed and set aside.
