Unfortunately, we cannot identify what rollers you need based on this information. We would need to see pictures of them removed from the door, along with dimensions.

See attached images.Is 81005 correct? Your literature indicates this is the replacement for my Acorn Series 400 door.

No, I don't believe the 81-005 is the right match. Not all Acorn doors use the same hardware, which is why it's important that you match up your hardware to our pictures and dimensions. The 81-005 is very different than the picture you show. I think you may want something more like our 81-033.
A quick learner from Raleigh NC says:
My Label looks identical to this one. I have not yet lifted the door out. Did 81-003 end up being the correct part? And I would love a video link for this particular part replacement. Thanks.

Tom from SWISCO responded:

The label shown above doesn't have any information regarding the roller itself. You may have the suggested part, but in all likelihood you have something entirely different. You need to remove the original from the door to know for sure. There is no getting around it, unfortunately. That's the only way forward.
