We learned a long time ago to only travel with good PLASTIC wine glasses, but like so many other items they get knocked over in cabinets. We have the 337RLS unit with the Hutch. I used a router to build my racks, but Amazon sells them unfinished and you can cut them to fit before staining. It doesn't solve the problem of them sliding out while traveling, so I put 2 brass screws into the rack and used my wifes hair band to hold them. We put racks on both sides so we have 6 glasses. ALWAYS have an extra hair band in a drawer someplace in case one breaks or gets too weak from usage.
