window Crank

Your operator cover looks like our 39-152, which is Andersen, but I'm not sure about the operator. Could you remove the operator from the window and show us a picture of it by itself? That would be a huge help.

I'm afraid it's still difficult to determine without seeing it out of the window. Many important details used for identification are obscured. Take a look at our selection of Andersen casement operators and see if anything here is a match.
