I have a bi-fold cabinet full overlay door for which I need a left-opening mechanism (slide or arm). Door is ~17" total, each side is 8.5". I can't seem to locate anything. It's not a corner cabinet it's flat but in a tight space and needs to be accessed from the right side. So I built bi-fold doors expecting to find a good mechanism for it -- I have the SFD-3L-L Self Folding Door Mechanism from Sagatsune but the doors are too narrow for its use. Ideas?
First thing is, never build doors for something like bi-fold hardware without having the hardware in hand and testing it on a scrap to determine the exact fit. Been there, done that. Even the specs that come with some of that hardware are wrong and don't fit as claimed. You get the hardware first, then you make the pieces to work with the hardware.
The other option is to modify the hardware, which I have also done plenty of when the hardware didn't work or fit quite how I wanted it to, or simply wasn't any available to do what I needed.
Beyond that, I can't help you since I really don't know what your issue is from your vague post and lack of pictures.
