Thanks for reaching out to us. I couldn't cross-reference this number to a particular window operator, unfortunately. Would it be possible for us to see a photo of your operator with the window open so that the arms that move the sash are fully visible? That's the best way to narrow down some options. |

Thank you for the photos, Linda! Our 39-381 appears to be our closest match. The link arm is 6-1/2" when measured as shown below. See how the specifications compare with your old operator. Note, the 39-381 lacks the offset that your old operator has on its link arm. This discrepancy may or may not be an issue--we've had customers have success and failure in this situation in the past, so I can't make any guarantees. You could try installing them to see if they work as is; if not, you could see if you can reposition the stud bracket on the sill to make up the difference. Let me know if you have further questions.
