Hi there. I do not know the ultimate source for this. I designed this kitchen almost 20 years ago and at the time I purchased it from another client. I would google "round chrome ceiling mounted potrack" and see what comes up. You could also approach a local metal crafter and see if they could make something similar for you custom? I have done this several times for various clients in order to get something of quality. It's not as complicated as you might think. Best of luck and thanks for reaching out. It is a signature little piece. Thx for noticing the details!
