This is 1 of 4 rollers from the door. Looks to be a 1? steel roller about 1/4? thick by about 2 1/4 inches long. Need to replace as being will not stay lubricated.

Please see our 84-066 roller. This looks like a pretty close match to me, but you may want to go over our dimensions to make sure they're the same.
