Hi, I'm trying to identify the correct crank to purchase as a replacement. Can someone help me or point me in the right direction? Thank you.

Thanks for posting. This awning operator might be either our 39-083 or 39-140, depending on the 'wingspan'. See the diagrams below for comparison. Let me know if one of these match what you have. For a new handle, see the 39-114L sold separately.
