Channel Balance Stamp

A handy person from Albany, NY says:

I've gone through your website and determined that I need a 25" Series 370 Channel Balance Product Code: S370-25.

My problem comes with selecting the weight of my sash. "151" is stamped on my channel balance.

Any idea what weight that means?

Hello, Ryan. We actually have a chart on the S370-25 store page. All you need to do is weigh your sash on a scale and match what you get up to that chart.
