Looking to replace awning operators in three windows.

I watched your video and it looks relatively easy to fix. I don't know what sizes to order.
The handles on three windows are broken. I believe the width of each window is approximately 21 1/2 inches. I believe the extended, open window, is approx 11-12 inches.

Thank you!

Thank you! The dual arm crank and handles were the perfect fit. Your video made them so easy to repair. I can't thank you enough.
