Get thee to a real hardware store. They will order you johnson hardware (it’s a brand) hardware for either bifold or multi fold depending on what you choose. What you have shown is multi fold which is four 12” doors per side- I find that a little rickety. I would prefer bifold with two 24” doors per side (depending on your clearances etc)

I agree to go to any big box store and they can help. I also think 2 panels on each side is a good choice

That said?

I'd get a decent handy man, or a contractor and do two sets of 24" swing doors, and just convert unless you have little or no clearance in front of the closet.

You get 99% view when all four are open.....and it's a simple conversion with no shaky foldy anything: )

But I loathe all bi fold.....just me. This was a SEA of rickety bi fold. The swing sit up on a base, for a more built in feel.
