What is the size of the bore hole for the 39-375?
Is it 11/32" or 3/8". I bought what you recommended (39-107FK) but the bore hole is too small. I need to replace a folding crank with stamp of C 1080-3A.
Thanks very much

Thanks for reaching out to us. The hole size on the 39-375 is identical to the 39-107FK which is 11/32". We may have another option for you but I'm afraid I can't make out the exact hole diameter from just a photo of a ruler. They tend to be more precise than that. Would it be possible for us to see a photo of your operator with the window open so that the arms that move the sash are fully visible?
