old windows




Hi there!
Thank you for reaching out to us. Can you show us a photo of how this balance connects to the sash at the bottom corners?
I'm thinking our Series 500 spiral balance and 17-012 bracket may be the way to go. We've used this setup on old wood windows and find it to be a reliable and straight-forward solution but I'd like to see photos first just to be safe.




Thanks for clarifying. I believe you have a very old Air Control window. The bottom nylon sash clips are the 17-014 and 17-015. The balance system will be Series 300 with either the 15-011 nylon shoe or the 15-020 nylon shoe. In order for us to determine the best match, can you remove an undamaged shoe and show us some photos?
