This roller looks like the 81-133 except the 81-133 has a track cleaner that looks like it adjusts up and down and mine does not have a track cleaner. the other measurements are the same. will the 81-133 work?

I agree, the 81-133 is a good match. The track cleaner is spring loaded, so it won't interfere with the movement of the door.
