Window crank knob

Question

Hello,

I have a milgard window that needs a new crank operator to open and close the window. I removed the operator and took a picture and I will need to install a new one. Please refer to the attached picture and let me know which one I need.

Thanks for posting. This looks like the 39-092 ROTO short arm operator, which can use a crank handle like the 39-224. The other components of this assembly, such as that bracket arm that connects the short arm to the sash, are no longer available, so you will need to reuse the old bracket arm assembly if possible. Let me know if you have further questions.
