My channel balances are from a philips 1993 single sash window, no tip out. The channel is 26 inches long and 1/2 in wide. The window sash is 45 in by 29 in, so the window is heavy, vinyl double pane glass.
I think I need channel balance 380. But not sure. See previous post.
I also need a top sash guide. Thinking it is 18-008.
