No color tips anywhere. Standard contractor grade windows.

Hello! It looks like you have tilt window spiral balances. Without a color tip, your only option is to remove the sash from the frame and place it on a scale. Then, look at the chart we show on the S900-29 store page. That tells you how much weight each color tip option supports.

Well that's easy, but is that all there is to it? What about friction and the like?

Yep! Friction is accounted for. The only thing that I can see causing a problem is if maybe you changed to a ticker weatherstripping at any point in the past, but that doesn't really have anything to do with the balances.
