Crank handle on awning window

Thanks for writing in! Are you only looking to replace the crank handle? If so, the 39-232 Roto Folding Crank Handle Should work for the repair. To confirm, you'll need to take a look over the specifications.

If you are looking to replace the entire operator, I'll need to see a photo of the arm(s) and how the operator attaches to the bottom of the window sash.
