You might be best to contact them and ask how you can go about placing an order. I knew what size of tanks I was needing to support so I just ordered the channel, bolts and brackets accordingly. If you tell them the dimesions of your tanks and weight being supported, they should be able to tell you what you need. They may not sell directly to the public but they must have retail outlets that do. I think the stand cost me around $250 CDN.
