pivot bars
Looks like your Simonton pivot bar product # 26-336 except the bump on the end. My bars have a raised rectangular bump at the very end which goes into shoe. The Simonton bars will not fit into my shoe.
Thanks for writing in! You are correct. The 26-336 Simonton Pivot Bar is an updated of your pivot bar but it wouldn't be compatible with the shoe. Your exact pivot bar is no longer available, unfortunately. The good news is, there are a few options available to you to make the repairs in the window.
The first option is that you can shave down the rounded edge on the pivot bar so that it will fit into the existing pivot shoe. Although, you should be aware that you would not be able to return the pivot bars once modifications have been made to them.
The second option is that you would need to replace the entire balance system. I am happy to provide you with those details if your would like to move forward with that option.
Please let me know!
