Hello,

Your balance reminds me of the S751-35 channel balance. Take a look and see how the specifications compare. Based on your 34 RB stamp, you may need the 34R strength option but I would suggest weighing your window sash to confirm that it falls within the 15 to 24 lbs weight range. Thank you!
