Bifold metal door top pivot. Also top guideline.

Hey Debbie. Can you clarify what you mean by also needing a separate top guide pin? Otherwise, i think the 21-018 or possibly the 21-065 are what you're looking for. Let me know what you think.

The 21-065 has a pin that is 3/16" in diameter. Or do you mean the cap? If so, clarify the dimensions for both the cap and the pin for this last pivot and let me know. 

Apologies; thanks for clarifying. It would be a bit unusual for the same bifold door to have different sized pins and caps on top honestly, which is what threw me off. Is this pin from a different door? If the cap has to be bigger in diameter I am wondering if something like the 21-042 is a better match; but this is not a Fenestra product. I am forwarding this discussion to a senior colleague of mine who knows more about these doors than I do; we'll see if we can come up with anything else for you.

Hey Debbie, thanks for bearing with me. I've check with some of my senior colleagues about this. Since this is a Fenestra door, you would indeed use the 21-018 pin with the 21-256 spring and 21-156 locking push nut. If you need the bottom threaded adjusting pin, it would be our 21-019. The last photo is another type of Fenestra pin, which we are looking into seeing if we can identify. Please bear with us a little longer, and we'll get back to you as soon as we can. Many thanks. 

Good news! We've found this part and are bringing it in for you. We'll let you know the moment it becomes available. 

Sure thing. You can order the other parts now, or you can certainly wait until we bring in this other pin for you. Let me know if you have any other questions in the time being.
