AND, because of our proprietary production technique, we can make the intermediate (center band) any size you want. They used to be 8mm in size with no option for change. What we have found is that many people would like one that is a little more generous like 10mm. You asked for it, we provide it. For us that’s how it’s done. It just takes a call from you to get you started. Call Dale at 262-534-6090
