Thanks for posting. I'm having a difficult time finding these rollers. Can you give me a bit more information? I'd like to know the thickness and height of the roller housing. I will also need to know the roller diameter. Thanks!

I took some measurements with a digital caliper, here they are:

Length:3 1/32
Width: 23/32
Height: 1 19/32
Wheel: 1 43/64

The door handle is stamped with:
Patio Magic by Daryl Products Co.

Thanks for the help.

Thank you for getting back to us. I think I recognize these rollers. If they're what I think they are, then the company that made them has been out of business since the late 70's. The door itself was discontinued in the 60's. We may not be able to find an exact match for you. However, I would start by looking at our 81-032 or 81-038. Carefully compare these to your hardware and see if you could get either to work.
