This is the shoe that goes into my apartment windows. Only one of four may be usable. I have also included a photo of the spiral balancer and the end of it. Which I can't find online. The balancers are ok I think. I just need shoes.

This shoe looks like a good match for our 17-059. Look it over and let me know if you agree.
