I don't have a pic handy, but search for 'furniture grade PVC'. There's companies that sell the pipe in different colors, along with all sorts of connectors, wheels and so on. You can make all kinds of things with that stuff. Just pick a pipe size that will handle the weight. I make products myself, so I have a hard time paying guys like Uline a ton of money for such basic devices. Unfortunately, anything remotely considered a commercial product... they really try to jack up the price. Some of the commercial shelving and other stuff out there, is ridiculously expensive.
