Metal Bifold Door parts missing

Thanks for writing in. Can you give us the diameter of both the pin and the cap? Also, do you by chance know the brand of the door? With this information, we'll do our best to narrow down the right replacement parts. Many thanks.

Thanks for these photos, they're a huge help. We believe you have the old style Float-A-Way bi-fold door. These aren't available anymore, but the good news is that we carry the newer style pins. See our 21-022 spring loaded guide pin with a 7/16"diameter nylon cap, as well as our 21-023 bottom threaded adjusting pin and 21-024 top pivot pin. The black nylon pin housing hook locks into the hole next to the pin hole.

Let me know what you think!
