Hello, It looks like you have either our S351-28, with a 15-002 bottom attachment, or S390-28, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2740 spring strength option for your replacement balances. Comparison of the S351 and S390 balance shoes.
It sounds like you also need new top sash guides that hold the balances in place below the window sash. There's a good chance that we can supply a replacement for your guide, but we would need to see one of your undamaged guides removed from the window, including dimensions, to compare to our inventory. Thank you! |
