Many thanks for your correspondence. My guess from your photos, you might have a Paniflex bi-fold doors. They are very popular in NYC. If that's the case, then the bottom corner threaded adjusting pin would be our 23-101. The top pivot pin would be our 23-100. Finally, the top and bottom spring-loaded guide pins would be our 23-099. Please compare and let us know your thoughts. |
