Hardware for Old Bi-Fold Door

Hello,

I'd suggest starting by comparing the 23-450 through 23-456 tracks to yours, depending on the length you need. We can't be sure of the top pin you have with the original still installed, but the 23-121 pivot guide is commonly used with these tracks. Review the specifications to see how they compare to your original hardware. Thanks for posting!
