Parts question

Hello there. I'm confident we can help you replace these bifold door parts, but I'd like a little more information to narrow down what you need. First, can you tell us the diameter of the pin? Can you tell us the diameter of that nylon cap or 'hat' atop the pin? Finally, is there any manufacturer label on the door you can show us? That would help a ton. From there we'll do our best to find what you need. For more information about how we identify bifold door parts, you can read this guide here.
