Track width

A quick learner from Chicago, IL says:
I am replacing my bifold doors with new doors and the track that is currently there is larger than is compatible with the doors that I am going to install. I need a track that will fit a 7/16 size pin, but there is not a width listed on these tracks. Are your 23-250 the correct tracks for my doors? I need to install 2 30'' doors for a 60'' opening and I also have a 96'' opening that I need to fill. These are my doors:

Thanks for posting. Would we be able to see the pins used in your door now? The 23-520 can work with the 23-114 top roller guide, or the 23-130 slide guide with the 23-112 top pivot pin. Compare these parts with what's in your door now to see how well they compare.
A quick learner from Chicago, IL says:
My pins look like the 23-112, but more like the 23-121 because of the plastic casing. I ended up ordering these, but I'm still not sure they're right:

60" Bifold Track, 4 Door (7/16" pin) 23-455
Top Pivot Guide, 7/16" Diameter 23-121
Bottom Threaded Pivot 23-135
48" Bifold Track, 4 Door (7/16" pin) 23-454

I'm really not sure either. If you'd like, you can send us pictures of your existing hardware and we can do our best to confirm. We would also need you to measure them for us as precisely as you can.

I don't know how to measure the size of the pin.

I'm afraid the 23-455 and 23-454 will not work. Did the 23-135 bottom threaded pin fit in your door? I'm afraid we don't have the pin you show. That's actually kind of a weird one. This probably accounts for why you're having a hard time finding this hardware. It may be a unique setup. If you need the nylon cap, you could consider our 21-100. I would also recommend one 23-456 and two 23-454. The pins that go in there are our 23-121. Please review and get back to us on what else you will need.
