The roller I removed is the same dimensions as 81-138, except mine has 1 1/4 inch wheels. Will the 81-138 work? An eighth of an inch in diameter is only a sixteenth of an inch different in radius, I should be able to adjust it up, shouldn't I?

Thanks for posting! Have you seen our 81-030? This is similar to the 81-030 but has 1-1/4" wheels. Would that be better?
