Which folding crank will work?

Question

I have no idea what brand of window or crank mechanism this is, but I wanted to add folding handles to them. Can you tell me which ones would fit? The splined shaft appears to be 11/32" and has 12 teeth. Thanks

Thanks for writing in! The 39-205 Truth Folding Crank Handle should work for your repairs. It has an 11/32" spline measurement. I am confident this should be the handle you need.
