I have a house with many sliding glass doors. They are of early 1980's vintage. The rollers on some of the doors are worn out and need replacing. But I am having a hard time finding replacements.

The only data I have is from the rollers themselves. They are marked"
A-S
8188.

Anyone know where I can get replacement rollers for these doors?

Thanks

I would check with your local hardware store for a universal replacement roller, Since your not sure what kind you have
