Hello,

We'd be happy to look into this for you but your balance is a bit too damaged to identify. To get started, we would need to see an intact pulley clip attached to an undamaged balance, as well as the pivot shoe that the clip attached to in the window. We'll also need to know the exact weight of your window sash that the balances support to confirm the strength option needed for your replacements.

It also looks like your balances may use an s-clip like the 19-029 or 19-030 for installation in case you need more of this as well. Thank you!
