Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.

Hi Tom,

Thank you! I will try to measure it. Also, how can I find out what stamp option to place order?

Based on your stamp, you could consider our 2730. However, you should weigh your sash and compare it to the options we show listed under each specific balance to determine what's best.
