parts for steel bi-fold doors

A quick learner from Louisville, KY says:
I'm trying to repair 2 Benchmark steel bi-fold doors. One is 3 ft wide by 8 ft tall; the other is 2 ft wide x 8 ft tall. The top pin on the 3 ft door needs replacing (on the leading edge) and the top and bottom pin on the 2 ft door needs replacing (on the leading edge).

Paul from SWISCO responded:
Are you referring to the guide pins for your Benchmark doors, I believe you can use our 21-042 or 21-044 . If you need the bottom threaded pin, however, consider instead our 21-002 .
