Hello CraigThank you for your question. The KB/ DB rack is flip-able. Therefore you can flip the rack on one side, which is suitable for dumbbells and the flat rack on the other side for kettlebellsRegards

Hi Gen, this is part of a modular configuration and you can add or remove components as you need. You can reach out to our commercial team directly to obtain an accurate quote. commercial@treadmillfactory.ca

These shelves are modular and customizable. You would be able to purchase a third shelf for this rack. Please contact :1.888.469.3031 for pricing or order inquires.

It can be done, you can use the 6' uprights but we would strongly recommend not using the wheels and having the unit bolted into the ground instead.
