Need this part
Thanks for posting! The hardware you have pictured here is the window pivot lock shoe. I believe it can be replaced with the 15-167 but you'll need to compare the dimensions shown below.
It may be a good idea to check for any damage to the window balance to ensure that it doesn't need to be replaced as well.
Unfortunately, that isn't the way these balances and shoes work. They are two separately functioning pieces of hardware that work in tandem with one another.
I'm happy to recommend a replacement for the balances; however, I'll need to see a photo of them removed from the window. To identify the correct replacement, I'll need to see the attachments at the top and bottom of the balance and any stamps that could be on it.
Please don't hesitate to reach out with any questions you might have in the meantime.
