The roller on the opposite side of this drawer came off and disappeared during our recent move. Diameter is 3/4". Width is 3/16" at the rim and 1/4" at the hub. No visible markings. The track and the roller seem to be pressed or riveted. I'm sure I will have to improvise the attachment. I needed a roller several years ago for a steel drawer and your shower door roller fit perfectly. Hoping for the same kind of match here.
Thank you
