Hey, thanks for posting. If all the balances have the same attachments, this should be simple! I've narrowed your balances down to two possible channel 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

Sure! In this case, I recommend the following stamp options:
-15B would be 1520 -12B would be 1220 -24B would be 2420 -21A would be 2110 You may want to weigh your sashes just to ensure that these are the correct choices. We have a list of options for each balance that shows how much weight each can support. |
