I've found this grill works for multiple purposes. In fact most recently I've been using this as a baking coal rack for the 8" Firebox Ultra cook kit.
Also this is sized specifically for the 2 quart billy baking kit as a pan rack.
Can be used as an smoker grill in the 2 quart pot if you want to try smoking in your pot. (see video below) This makes the pot really messy and requires a lot of cleaning afterwards.
Also can be used as a standard grill over your fire.
