I have a 15-gallon Megapot with a stainless 1/2" ball valve and lid. Great condition. This has served me well, but I no longer need it.
I purchased this rack from an avid brewer to improve my homebrew setup. While it works great, I have changed my brewing setup yet again, and no longer need the rack.
4 swivel and locking casters make this easy to move around. Tabs welded to the rack accommodate 2 square-frame propane burners, or can be modified to work with your preferred burner. While the main shelf can hold 3 kegs, I found it works great as a 2-tier system (picture with kegs to show setup - kegs are not for sale). If you have the vertical room, you can even use it as a 3-tier system. I have drilled holes on the floor that hold 2 March pumps in place, and electrical or plumbing additions are easily attached with metal screws or bolts.
The dimensions of the rack are 44.5"w X 29"d X 72.5"h. The main shelf is 41" from the ground.
