Hi there!
Thanks for reaching out to us. I don't recognize this pivot bar at first glance. Please allow me to consult one of our senior experts. We will reach back out ASAP.
We have an offset tilt bar like yours, the 26-306, but the mounting hole is set back 2". I'm not sure your sash allows that. We also have a straight pivot bar, the 26-241, where the rear hole is set back 1-3/4". We don't believe the offset is critical in the operation of the window. Take a look at the specifications and see what you think.
Hmm! Would it be possible for us to see a photo of the pivot shoe?
This pivot bar should work for you since it's designed to be used with the 15-180 shoe. Re-drilling holes might be necessary if one of the installation hole placements doesn't match up. That may not be the case here looking at your illustration but you can compare the dimensions to be certain.
No problem! Please let us know how you make out with your repair and if you have any future hardware questions.
I'm very happy we could help! You know where to find us if you need anything else!
