Hello,

We can't be sure with the balance still installed but it looks like you may have the S751-33 ribbed channel balance with a (32TG) strength option to support a sash weight between 29-36 lbs. I would recommend removing your balance and confirming the exact weight of the sash to confirm if this would work for your application. Thank you.
