Bay window crank

Hello, thank you for posting,

We should be able to assist, but to further review, we will need to see the window open where we can see the arm attachment(s). From there we can get a clearer idea of the style needed for the window. Thank you! 

Great thank you,

Please review the style and dimensions of the 39-031 and 39-032 or the 39-155 and 39-156. The main difference is the length of the short link arm. Compare the measurements and orientation to your original to confirm a good fit! Let us know if you have any additional questions!
