BOTTOM TRAVEL

I am leaning towards our 21-041 bifold track. Before we can confirm that, we would need to see some close up photos of your door guide pin, as well as the top and bottom pivot pins.

Thank you. You have old Benchmark doors that use 21-002 bottom threaded pivot pins and 21-044 spring loaded guide pins. The tracks you can use are 21-401, 21-402, 21-403, or 21-404. The tracks come with 21-200 pivot brackets, but you will need 21-277 bumpers to help keep them close.
