Roller hardware 70's windows

Thanks for posting. I am afraid there's no reliable way to identify window rollers without seeing them removed from the window, along with dimensions. I should note that window rollers are very hard to find replacements for, since many designs are no longer made, and replacements must be exactly like the originals in order to work. If you can get us photos of the rollers though, we'll do our best to see if we have something that can work for you.

Thanks for getting back to us, but as Bob mentioned, we would need to see your roller fully removed from the window and have you write out the dimensions to determine if we carry anything similar.
