The uprights measure true 3" x 3" which is EXACTLY 76.2mm x 76.2mm, instead of the typical 75mm x 75mm uprights of other brands' imported racks. By matching the same tubing specs as many of our American competitors, you are able to mix and match attachments freely without needing to stick to one brand - hello, open ecosystem!
