These are Keller windos

Hello,

It looks like your windows might have coil balances based on what I can see in your photos but I would need to see your balances removed from the widow, along with any other parts you need to replace. Thank you!

You're absolutely right. Your pivot shoe is our 15-105 and it attaches to a channel balance. We'll need to see an undamaged balance fully removed from the window to confirm which one you need. Thank you!
