Anderson 7073a
Thanks
Thanks for writing in! The Andersen product information you provided from your casement window operator brings up a few different hardware recommendations. To be able to properly narrow down the replacement you need, I will need see a photo of your existing operator.
Are you able to provide a photo of the hardware?
Thanks for the photos! We do not carry an exact replacement match for your existing Andersen casement operator but our 39-366 9-1/2" Single Arm Operator could potentially work as a suitable replacement. The opposite handed version is the 39-365. To confirm if these will work, carefully look over the dimensions and compare them.
The compatible handle is the 39-114L Crank Handle.
Since these operators have a stainless steel roller connected to the end of the arm, you'll also need either the 39-504 or 39-512 track operator.
