You are showing a National Bi-fold door. The top pivot pin in your photo is the 21-041. The other pin that's used is our 21-072, a spring loaded guide pin that is used for the top and bottom track. Lastly, the bottom adjusting pivot pin is our 21-046. Look over all the parts mentioned and see what you think. |
