Hello, I'm planning to do an 'orange mod' on my hevos powerset. I don't have orange cabinets, so I was wondering if there are little knobs under the cabinet to rest on the floor. I think the corners that are used are not stackable are they? Maybe you know what is the exact corner that is used on the cabinets? Also I would like to know what the distance is from the front of the cabinet and the black piping around the cabinet. thank you all!
