replacement crank for oldach window corp windows

Thank you for reaching out to us! I'm afraid I couldn't cross-reference the number you gave here. Can you write out the hole diameter for the handle? It would also be a huge help if we could see a photo of your operator with the window open so that the arms that move the sash are fully visible.

Thanks for the additional photos and information! Our 39-031 & 39-032 or the 39-155 & 39-156 appear to match what you have here. They're compatible with the 39-114L handle which fits an 11/32" spline. We also sell the 39-205 folding handle if that's something you prefer. 

My apologies! Yes, we have the 39-102 which should work well with your operator.
