Looking for this channel balance. Doesn't seem to match any that you have on your site. It is 1/2 " wide and 29" long. The window weighs about 30-40 pounds and is non tilt.

Hi there!

It looks like you have either our S351-29, with a 15-002 bottom attachment, or S390-29, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a spring strength option of 2850. 

If you have any further questions just let us know.
