I bought some galvanized angled channel, and some casters at Home Depot.I'm sure a welded SS rack would be a bit more top notch, but this was closer to my realm. I wanted to make the whole setup as small as possible, so that I would be able to roll it from inside my apartment out onto my patio. The overall length is 54", and it's 66" to the top of the kettles. I've added wood shelves, which I treated with water sealer. My wife saw it and asked me if I didn't get an erector set when I was young...Women.
