Replacement Tracks and Hardware for metal bi-fold doors dating back to mid-1970's

A handy person from PA says:
I sent an email inquiry earlier this morning.
Attached are two photos that I took of the top and bottom ends of the bi-fold door set, without the hardware in place.

Can you discern whether your hardware will fit on these doors, please? I would much prefer to make these doors work, rather than buying new ones that are much shorter (requiring a bulkhead to be constructed) and are much simpler in detailing that may pose an eyesore with others on the same floor of the house.

I would be willing to purchase both tracks and all pins, plungers, etc. so everything works as intended, instead of mixing and matching old and new parts.

I have at least a dozen more similar sets of bi-fold doors in the home - all full height floor to ceiling, at all closets.

Similar height replacements are outrageous custom orders at typical building supply stores that send the cost from $100 to over $300 per set.

I'd be willing to cut and fit-on additional steel plates to make your hardware work, if necessary.

The plastic piece in the photo appeared similar to one of your products, which makes me optimistic that something should be able to work.

Thanks again,

Thanks for posting, John. I believe that you have the old Slimfold closest door. See our 21-001 bottom threaded pivot pin and 21-007 guide pins. The pivot block they used was like our 21-200 . It also looks like you have a steel track and we carry a variety of the aluminum tracks that might work for your doors if you need to replace. I've made a list on the right side of this page you can use as reference.

Thanks for writing in. I am sure we can help you locate some replacement hardware. Before we start, could you describe what kind of parts you are looking for? And, are you able to send us some photos of the parts you are looking to have replaced? This will help us identify what type of hardware to search for.

We need photos of the doors, and dimensions of the parts in question, to help you with the door hardware. There are many closet door companies using different hardware, and we need to see yours to match it as closely as we can. From there we will do our best to find what you need. Many thanks.

We'd like to see your bi-fold door pins to confirm if our 21-401 track is the correct replacement for your door. Thank you!
