This listing is for a set of 4 matching Louden Machy ( Machinery ) Co door rollers [ Patd 1901 ]  made in Fairfield Iowa, that are in very good working condition with no chips or cracks complete with antique bolts for the hinging door brackets. The 2 pcs of track each measure 96” and all of the wall brackets are there and well connected. The rails measures 1 1/4" by 3/16" thick. I would not recommend for someone to use this hardware if the doors was to weigh over 200 pounds ( each ). These rollers come with a full 2 year warranty. These rollers should be operating good 75 + years from now.
