Thanks for posting. I'm afraid I can't entirely make out these rollers from the photos. Can you show them to me removed from the door? Can you also provide the width and thickness of the outer assembly, as well as the diameter of the wheel(s)? From there, we'll narrow down what we need. Many thanks.
