replacement bifold parts needed

Hello,

We'd be happy to look into this for you but we would need to start by seeing the pins from the top and bottom of both of your doors uninstalled to compare to our inventory. Written-out dimensions including the diameter of the pin and cap are also important to narrow down your options. Once we can identify your pins, that will help us determine if we carry tracks that would work with your original hardware. See our bifold door guide here to assist you. 

It looks like you have old-style Slimfold doors. These can generally be used with the 21-401 top track with 21-007 spring-loaded pins for the top pivot and top guide pins.

For the bottom corner pivot bracket, you can use 23-316 with the 21-003 bottom threaded adjusting pin. Review the specifications of each part and see what you think.

Dimensions for 21-003

We also carry the 21-404 version of this track that measures 4' long. These parts would be compatible but we can't make any guarantees since you mentioned that these are not the original doors for your closets. If you decide to give it a try and run into any issues, our return policy can be found here. 

The door shown in photo 732415 is Slimfold and the parts I recommend will work. The door in photo 732417 is Benchmark, which is similar and should also be able to use the parts we mentioned. For the bottom jamb bracket, you'll need the 23-316 and 21-003 pivot pin.
