Corner key / brace?
Hi there!
Thanks for reaching out to us. I'm afraid we don't sell a match for this pivot bar.
We have one idea that may work as a substitute, but we've never tested it out ourselves. At this point, it's just a hypothesis. Our idea is using our 26-068 straight pivot bar and installing it with a screw like our 33-073. The hope is that the vertical post on your old pivot bar isn't necessary and that you could get away without it. The long holes on the 26-068 also allow more flexibility in terms of aligning it with the hole already in your sash. Look it over and see what you think.
