I need the handle only replaced on my Anderson window

Thanks for posting. This Andersen cover and folding handle is no longer available. Andersen suggests that the 39-459 kit might work as a substitute, but I cannot be certain. Give the dimensions below a look, compare to your old hardware, and let me know if you think this kit could work for you.
