Alside casement crank

Thanks for writing in! This crank handle can be replaced with either the 39-114L Crank Handle or the 39-205 Truth Folding Crank Handle. They will both have an 11/32" spline measurement.

Take a look over each of them on the website and see what you think.

If you are looking to replace the crank operator, I'll need to see a photo of the entire mechanism; particularly, the arm(s) and how the operator attaches to the bottom of the window sash. You'll need to open the window to obtain this photo.
