No part numbers. Two rollers per door. Ray Door manufactured by James Ray Company of Wichita, Kansas. Firm no longer in business.
Thanks,

Hello! Your roller does appear to match our 81-004, yes. At least in terms of design. You should still check our dimensions to ensure that everything lines up. If they differ, let me know and I can try to look into alternative options for you.
As for the weatherstripping, I'm afraid I don't recognize that style. Could that sample possibly be damaged? If so, can we see an undamaged shot of it that shows the end profile?
