The length of the steel channel is 28". Width 9/16". Depth 5/8"

Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Thank you! In that case, I recommend that you look at our S350-28 channel balance. I would also recommend the 2730 stamp option, based on your image. This can support a window sash weight range of 13 through 19 pounds. Does your sash's weight fall within that range?
