Hello, thank you for posting, You have a very old Strato Bi-fold door. For your top & bottom spring loaded guide pins, you can use 21-091. For the top spring loaded pivot pin, you will need to combine the 21-026B plain 1/4" pin with the 21-250 spring and two 21-155 push nuts, one for the top and the other to lock in the pin to the door. For the bottom threaded adjusting pin, you can use the 21-003 pivot. |
