Hello,

Your channel balance resembles the S751-32. I would recommend checking an undamaged balance from another window to confirm that it uses a rivet at the top as shown below. Your replacement balances will need 31TG strength options to support a sash between 29-36 lbs.

We also offer the 19-029 short and 19-030 long detach clips commonly used with these balances. Take a look and let us know if you have any other questions. Thank you!
