The pin appears to be 4.25" long with a spring near the top and some kind of clip at the bottom. Th bottom diameter of the pin appears to be 5/16" . The diameter of the top of the pin appears to be about 1/4" or possibly 1/32" more but not less. (Ntt sure if it matters.) I don't see any plastic on the pins, but these pins are probably quite old

Thanks for reaching out to us. I see that you are showing us a National door top spring pivot pin that has been discontinued some time ago. Is this the part you are looking to replace or are you inquiring about the spring guide pins that travel along the track, such as our 21-072? Get back to us and let us know.

I am looking to replace it or find something I can use in its stead. Any suggestions?
