I'm confused looking at your photo. What is that black piece on top of the roller? Is there another part to the roller housing that you are not showing? It looks very small for a patio glass door roller. Could there be an outer housing still installed in your door?
A home owner from Flagstaff AZ says:
Attached is a different view of the roller. The door it goes to was made by Patio Enclosures Inc., now gone! It is: H 78 1/4" W 47 3/4". The black piece is the top cover of the rollers. This second pic gives you an idea of relative size and how the pieces fit.

I hope this helps. Again, thanks so much!

Thank you for your patience in this matter, Jody. I'm afraid I haven't been able to find a match for this. I do have a thought, though. I'm not sure if this will work for your door, but take a look at our 81-119 rollers and see if they could work for you. Also take a look at our selection of patio door wheels and axles. Maybe you can just replace the wheels.
