Window balancer

Thanks for reaching out! We can supply the replacement for this balance. Although, to narrow down the correct match, I'll need to see a clearer photo of the bottom attachment as well as a photo of the top attachment.

Please also provide a photo of the spring side of the channel. I'll need to see a photo of the spring and the cord (string) and how they're connected to one another.

Feel free to reach out with any other questions you might have!

This balance is a match for the S350-28 Channel Balance. Like yours it has a wingless top guide and a winged bottom shoe. 

Our 2740 stamp should work for your 27 4 stamp. It will support a sash weighing between 19 to 26lbs.
