I believe that you have an old Benchmark metal bi-fold door that uses a 21-002 bottom threaded pivot pin with either the 21-042 or 21-044 guide pins. See if this hardware matches up. For the track, see if you can use our 21-404. This measures exactly 47" for a 48" opening. They do that to give a 1/2" of play on each end of the door opening.
