Funny that I've never seen that product before but I've been experimenting with my version for the past year. Never posted anything as I'm afraid people might think I've lost my mind. So here it is, I'll add captions on the photos so hope you guys can follow.
SS railing attached to the charcoal grate using brackets. It prevents coal from coming to direct contact with the bowl and also makes arranging the coal a breeze.
Modified 2-piece stock pot allows for adjustable height.
The railing makes stacking the lump more convenient as I rarely, if ever use briquettes. I refer to it as "snake easy".
That's how it looks with the grate on. Legs are added to the grate so it sits 1 1/2" above the griddle. I'll probably add a lip later on the stock pot so it will extend slightly underneath the Arteflame griddle.
I trimmed 1/4" off the griddle perimeter to increase smoke flow around the edges.
I use this version on the Caliente stacker. Not sure which version works better as i don't smoke meat that often. Maybe just 4-6 times a year. Only advantage i can think of is the lesser amount of direct heat as the charcoal distance is much farther away.
