I'm replacing my hollow wood bi-fold doors with metal bifold doors. I looked at the replacement hardware I would need from your thread with similar metal bifold doors. My question is, will I also need to replace my track, or can I purchase a wheel cap that will work with my existing track?
Here are additional photos of the top of my track and bottom bracket. I ended up ordering the 21-001 and 21-007. The hole on my top track bracket is 1/4 opening. Will the 21-007 cap come off so I fit it in this hole without the nylon top? That is how I also hope to fit the roll guide onto one of the 21-007's as well. Also, on the 21-001 do you think the nylon piece will work okay in this bottom bracket? It's opening is 3/8ths.
