Hi there!

Thanks for reaching out to us. We're happy to look into this. Can you upload photos of the operator assembly? If we can ID that, we can determine the compatible crank handle.

Thank you! This looks like it might be the 39-083 or 39-140. The compatible handle is the 39-114L, but we also have the 39-205 folding style. Review the specifications for the mentioned parts and see how they compare with yours.

I tried that crank and it wasn't the right one so I am providing more pictures in hopes that someone may be able to help further.

It looks like your old operator is stripped, so you'll need to replace the assembly. The previously mentioned operators may be a match for yours, but you'll have to review the specifications to confirm the best match.

Your old handle is no longer available, but the 39-114L and 39-205 are the suggested substitutes.
