Norton Norax is the brand and model. They have a funny number system that represents grit on that line of belts. I think it's like 18x, 45x, 65x and blah blah blah. Anyhow one place I ordered belts from had em listed by grit too. I took a daggum sharpie and marked the inside of the belt. A couple of other manufacturers use the same system. I guess it's like standard vs metric. Atleast they are different colors. The 3000 is white and the 1200 is gray and I think the 600 is brown then the 220 is tan I think. Those are the 4 norax belts I have. Then I've got several others. The norton blaze ceramic belts are orange. The norton bluefires are blue. Then there are different grits in each model. I've got a 3m trizact structured abrasive that is a really nice belt. It translates to 220grit. Those structured abrasives run cooler.I just have a 6" belt sander/disk combo....I didn't know they offered 3000 grit. I've got some 600. May have to do a little research to see if mine can get those belts.
