bi-fold metal door parts

A handy person from Long Island, NY says:
I have an old metal bi-fold door that is missing some parts but in overall good condition. The pivot rod clamp, pictured, I believe matches your part number 21-154. Also, the bottom guide pin, pictured, matches your part number 21-001 and 21-005. Not sure which one is the right one.

You have the old Slimfold bi-fold door model. They have changed the pins to fit better in the door and track, so you would need our 21-001 bottom corner adjusting pin with the 21-154 clamp. The other three pins will be spring-loaded, our 21-007. See our video on installation and let us know if you have any other questions. Thanks for posting!
