Pella window crank 624X
That number doesn't match anything in our inventory, unfortunately. That doesn't mean that we don't have your part, just that that particular code isn't relevant to us.
I see you were looking at our 39-109B. Does this match what you have now? If not, can you show me a photo of your handle so that I can have a better idea of what you need?
I need 3 Pella cranks, copper colored, and the part number is X429, which seems to be the inverse of your NY inquiry. It is hard to tell if your 39-109B will work, as the head-on images don't quite jive.
I don't see anything in particular about your handle that would preclude our 39-109B from working. There are some minor differences in the shape of the base, but those wouldn't really come into play. What's most important is the diameter of the hole; in the case of our 39-109B, that'd be 3/8". If yours matches then you should be fine.
