I need a drawer roller that is 1/2" It looks like the picture I send to you. Thanks.

I'm afraid we do not have this kind of roller. It looks very old. You may want to consider using a new track kit entirely. See our 32-063 and let me know if you could use this as a replacement. Check out the video below to see how its installed.
