I have a number of windows where I need to replace the window crank operators. Do you have these replacement parts?

The assembly shown in your photos is an old version of our 39-092 Roto operator. You can reuse the original handle or purchase the new 39-224 . Unfortunately,  the link arm to attach the operator to the sash has been discontinued and must be reused. Take a look and let us know if you have any other questions.
