roller has 1-1/8" concave wheel, looks similar to the 81-086 but mine has bendable tabs on the roller body and a threaded hole on the bottom corner (instead of the top) to fasten to door bottom. please see attached picture.

Thanks for posting! The 81-086 definitely isn't it. This looks closer to our 81-032, but I'm not sure if this can work. There are a couple differences, like in the number of flanges. The wheel is also bigger, but in a lot of cases you can always adjust the door to make up for the difference. That doesn't account for the other measurements though. I recommend carefully going over the dimensions we show for the 81-032 and seeing how well they match up to yours. If they differ in any way, let me know how.
