Are the holes in the pivot bar threaded? I have Better Built windows and they are threaded. The 26-378 appears to be the correct size.

Hey there, thanks for posting. In order to install the 26-378, you'll need to use a self-tapping screw like the 33-074 or the larger 33-096. That type of screw will make its own thread in the pivot bar hole.
