pivot
Thanks for posting! We do not have an exact replacement for the pivot bar you have here but there is a chance we may have a suitable replacement. To confirm this, I'll need to see a photo of an undamaged pivot bar removed from the bottom of the sash as well as a photo of the compatible shoe it interacts with.
Please feel free to reach out with any questions you might have.
Thanks for the additional photos. For the shoe in your window, we'd typically recommend the 15-199 Pivot Shoe. We aren't sure that your exact shoe is available any longer.
The pivot bar compatible with the 15-199 is the 26-378 Pivot Bar which has a similar end to your existing pivot bar. That being said take a look over the dimensions, to determine if the installation hole placement is a match. The length should not affect the installation of the pivot bar.
