Window cranks have aged and cracked with use. Needing to obtain some replacements. Attached is a photo of what we have. The base, and the handle both measure just about 4" long.

Hello, thank you for posting,

Your handle resembles the 39-205 folding style that fits onto an 11/32" diameter operator spline. Compare the dimensions to confirm a good fit!

If you are in need of the full operator, we will need to see the window open where we can view the arm attachments. From there we can get a clearer idea of which style you have for a proper replacement option. Thank you!

Hi Lauren,
Thanks for helping identify the crank, that part looks correct to me. I think the crank and the attachment that goes to the window frame both will need replaced. I attached two more pictures, the handles themselves are stripping out, and you can see in the picture that the attachment itself is cracking as well. So I will probably need the part number of the attachment as well to replace the whole thing.

Thank you,

To further review, can we see an additional image where we can see a clear view of the full arm and how it attaches to the window sash? From there we can determine the correct fit for your window. Thank you!
