Roller replacement Help

A home owner from USA says:

Hi Tim,
Thanks for responding to my contact, I understand that you need more information, unfortunately the parts have no kind of stamped information on them, nor do the door they or install on. I didn't take any measurements because when I received your suggestion I had already reinstall the door for home security.
If you click on the link below you should be able to see the photos I took.
Thanks, Willie

Thanks for contacting us, Willie. We don't currently have a roller like this, but we are currently working on bringing something in. Hopefully it's a match! I will let you know the moment it is added to our catalog.

Hi Tom,
I would like to take this time to thank you for your support and attention shown to my inquiry. The 81-281 look's like a match,unfortunately when I received your Email I had already purched a new door. I just did'n think that roller could be found, after hearing so much, get a new door. Once again thanks for all your support.
