Hey there!

It looks like you have our S770-27 channel balance. To determine what spring strength option you'll need, we recommend weighing your sash on a scale. There's a chart on the S770-27's store page that will show you which option you'll need based on the weight of your sash.

If you have any questions just let us know!
