Wheels- need to replace

Question

Our back door was installed by Phillips Stayton, we need to replace this part but I don't know where to get it or what it is called.

Thanks for posting. The 81-056 is a good place to start; although I'm concerned your housing may be a bit taller. Could you confirm the height and thickness of your roller, as well as the diameter of the wheels? This will help us confirm the proper match. Thanks.
