Need help to identify part - single hung window spring

Quick Learner from DeBary, Florida

Length 24"

Markings: the number 2390 is stamped in a horizontal position, then the letters FG (horizontal) then the letters BSI in a vertical direction; then the number 34 afterward in a horizontal position. No other markings that I can find.

Need help identifying so I can place an order.

Thank you.

Hi Ken,

We can replace these balances for you but we'll need to see clear, zoomed-in photos of the top and bottom attachments to identify a possible replacement. I would also recommend weighing your window sash since (2390) is an outdates spring strength number. Thank you!

Thanks Casey - I've uploaded more pics, hopefully they help.
The aluminum rod is 24" long and 5/8" wide. The plastic inserts on each end extends the full length to 25" from tip to tip. Hopefully you can determine what I need from that. If you still need me to weight the sash I can do that. The house is not near me but I can make arrangements if needed.

Perfect. Take a look at our S395-24 channel balance. You'll just need to get the sash weight to choose a spring strength option based on the chart under our product description. Thanks for posting!
