Missing bifold door hardware

A landlord from 11230 says:
These are pictures my contractor sent me. He doesn't know the manufacturer of the door. Can you tell? What parts would I need to replace the existing hardware?

Hello,

I can't be positive with the pin still installed in the door but what I can see resembles the 21-050 or 21-058. We also offer the 21-108 pin cap separately. Take a look and review the specifications and parts that come with each guide pin to see which matches your original door hardware. Thank you!
