Hello,
I can't be sure since the operator arms that connect to the sash are only partially visible but I would recommend starting by comparing the specifications of the 39-146 and 39-147 Andersen operators to yours. If you notice any discrepancies, just get back to us with detailed photos and dimensions to help us research this further. Thank you!
