Pivot bar is for a Superseal window.The sash is mechanical. Remove the 4 corner screws and you have access to the tilt latches, pivot bars and the glass.

Hello,
It looks like you can use our 26-125 pivot bar as a replacement to your Superseal pivot. Take a look and let us know if you have any other questions. Thank you!
