Channel Balance Help Me

Thanks for writing in, Mike. See our S395-28; just confirm that the metal channel, not including the nylon fittings, is indeed 28" long. You'll need to select a stamp option. Look for a stamp code on the metal channel. If there is none, or if you are uncertain, weigh your window sash. We can then match that exact weight with one of the weight ranges listed alongside each stamp option on the product page.
