Can't find a match to replace this part
Thanks for posting. I've been having a hard time finding this roller, too. The issue is the screw tab bent at a horizontal angle like that. Most rollers we have in this style have a vertical screw tab.
Please give us just a little more time to look into this, I have a few other avenues I want to explore before I say anything for sure. I hope to get back to you soon.
I don't believe your roller is still available. We tried digging around for it but had no luck locating a modern source for these. I think it may just be too old.
You may want to consider our 81-269 roller. Compare the dimensions we show on its store page with your roller housing and see if they match up to yours. If the dimensions match, I'm hoping you might be able to bend that back tab up so that it can install on your door. We used to do this back in the day when encountered with a similar situation. Let me know what you think.
