two pieces of expanded steel tied onto the charcoal grate...about 3" high so it doesn't interfere with the pot
No need for a teracotta pot i just use the steamer pan...works great. Sit a pot on the steamer if you want but it's not necessary at all. This is a 9 lb butt i did in hours.
Put a handle on the vent if you'd like...nice and handy
The gold is nice also if you want to screw in a guru or iq
The top grate is 4 inches from the top and i have a 2nd one 3 inches above the steamer
