I live in a 500 unit condo complex and I am a repair contractor. We have new windows installed few years ago with different balance systems. Many are falling apart in large numbers. The windows are 25lb, and the length of the ballance's metal part is 26". The windows are very hard to close, so they might been oversized. The one on the picture is the better one (that is not falling apart) the "Inique" modell is falling apart in 50% of the windows. We need about 10 set for now, I'm certain more will needed, soon.
