Old metal bi fold door bottom pivot
I think we can help supply this pin, but I'd like a little more information before I recommend anything. First, can you tell me the diameter of the pin itself? Would it also be possible to see a clearer photo of the nylon cap that goes into the track? I would also need to know the diameter of that cap. Finally, do you have any idea who made this door? That would help us narrow down the list of potential replacements by a lot. Thank you!
Can you confirm those measurements? 3mm is coming up as less than 1/16", which is extraordinarily small for a closet door pin. Most pins vary between 1/4" to even 5/16". I would also ask you to double check the diameter of the cap.
You may need to remove this hardware from the door to get accurate measurements.
Thanks!
