Channel Balancers

A handy person from Fort Myers FL says:
I need two 30 inch Balancers . Markings on existing 2919 BS1 R M . It has a 1/2 inch channel, the top looks like a 19-005, the bottom like a 15-002 or 15-001. The color is like the 15-002.

Good morning, and thanks for posting. Looks like your top attachment is winged, while your bottom is not. Since this doesn't match any of our standard Series, your balance will have to be specially made.

Before I can work on that, though, I'll need to figure out what that bottom shoe is. The colors don't matter, only the size. Check out the image below and let me know what you have!

I would also like you to confirm the weight of the window sash. 2919 is not a standard option and we will need to know your sash weight in order to calculate spring strength.
