Hello. I have a broken part and hope you can help me find the replacement part

Thanks for reaching out to us. I'm afraid I can't determine a good replacement for your roller based on these photos. What you're showing here is just the internal portion of a complete roller assembly. The external housing appears to be missing. I would wager it's still in the door.

We will need to see the whole assembly together in order to find a match in our inventory. I would also like you to write its dimensions out for me. I specifically need the width and height of the housing and the diameter of the wheel. Please let me know if that will be possible.
