Hello,
I don't recognize this bifold pin at first glance but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. Thank you!
We carry a plain 1/4" pin for bi-fold doors, which would be our 21-026B, which is 6" long. The length shouldn't be critical but you can cut it down with a hacksaw if needed. If you can't reuse your old cone spring, our 21-252 should work for you. You will also need locking push nuts like our 21-155. I suggest ordering a few extra since they are easy to lose. Take a look and let us know if you have any other questions.
Hi Liz, we believe you can use our 21-212 pivot bracket for your door. The threaded pivot pin will be the 21-003 and the guide pin is 21-066. You might also want some of the 21-250 nylinders to help the guide pins slide through the door.
For the handle, take a look at the 22-003m which comes with a #8/32 X 1" screw.
