upper closet hardware Acme patent 3750337

Hello there. We were able to cross reference two pieces of hardware based off of the patent number you provided to us. Please visit our 23-196 bypass top roller assembly and 23-222C sliding mirror door top roller guide. See if these are the parts you are looking for. ACME was bought out by Stanley some time ago and since then Stanley has discontinued a number of their products as well as made alterations to the original parts.
