Marvin part is labeled "operator panel roller(tandem-adjustable)". Marvin part # is 10820000. What fits from Swisco? What about your #81-018? I need two rollers each.for two doors.
Thank you,
John

I'm afraid that we have no information on what this roller is or what replaces it. The only way I can confirm if the 81-018 can work for you is to see a picture of your own roller removed from the door.
