Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 351 or our Series 390 balances.
Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 351 uses the 15-002 while the Series 390 uses the 15-001. 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. Comparison of 15-001 & 15-002

You will have to remove your sash and place it on a scale. Once you know its weight, you can compare it to the list of options we show for each balance. If your weight exceeds everything we show, let me know and we can see if it's something that can be custom made.

Yes, a pair of 35" Series 390 balances with stamp option 3450 will carry a window sash weight range of 30 through and including 34 pounds.
This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |
