METAL BIFOLD DOOR

Based on your photo, your top guide pin looks like our 21-007. As for the bottom pin, it didn't end up in your photo, so I'll have to guess a little. If your pins look like 21-001 and 21-007, you can use one of our bi-fold door tracks: 21-401, 21-402, 21-403, or 21-404. If you don't have a 21-001 on bottom, let us know.
