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.
15-004 and 15-005

Thanks for the quick reply. It is the Series 380,. How do I determine the Sash Weight required.

Thanks

Usually a stamp of 29 A corresponds to our 2910 option, but you may want to weigh your window sash just in case.
