Sliding door roller

Hello there. Allen Stevens who made your roller is no longer in business. Take a look at the 82-032B on the web site. This roller is similar in dimensions. Looking at your roller I believe the bumps on the sides make the width around 25/32". The 81-032B width is 13/16" with the flares on sides. It's not much wider than your roller width. Take a look at the 81-032B and see if you think it could work for you.
