Here is our rack. We built it out of melamine from Home Depot; if you bring in your specs and size needs, they will saw it there for you. Any questions, please ask or PM me! Oh, it holds Sterilite 41-QT tubs. Heating is Exo-Terra heatmats on dimmers, though most people use flexwatt, this works for me. I too use the metal tape to attach the UTHs to the tub underside.
