Door is in North River Homes modular. Door is approximately 6'x6',and is thermopane with plastic divider between the sheets of glass. The modular was manufacture in 1985. Both bottom corners of the moveable door have Phillip's screws in them with a hole above the screw. I can't see any identifying marks on the door. It's 20 degrees outside so I can't take the door out at this time.

I'm afraid there's no way for us to identify your rollers from this information. There is only one way to know what roller you have, and that's by seeing it removed. I know it's cold out, and it can be a bit of a project, but there is no other way. 

If you can show us a photo of your roller fully removed from the door, I am confident we can recommend a match. You may also find the video below helpful.
