Balance part for 35" x 60" window

Hello,

Since your balance fittings appear to be non-winged, you have either our S351-29, with a 15-002 bottom attachment, or S390-29, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. Make sure to check a balance with an intact bottom fitting to get an accurate depth measurement.

You'll also need a 2830 spring strength option for your replacement balances, which will support a sash between 16-23 pounds. Thank you!
