Anderson 30-3442-20 angle bay window with 3 Narrowline double hung windows

Question

This 30 degree bay is from 1992. All 6 windows balancers need to be replaced. All 6 balancers are marked 11600-17 on the face. The 4 outer smaller window balancers are marked 627 on the mounting tab, the 2 center larger window balancers are marked 1031, also on the mounting tab. There are other numbers stamped on them but am assuming could be manuf. dates. Also, do they have to be ordered RIGHT & LEFT because the tension and cord distance varies between the upper and lower window sashes. Can you clarify all this for me. THANKS, Jeff

Hello Jeff. Let's start off by pointing out how great your windows look. Ok, let's move on to the reason you contacted us. For your outer windows, your stamping of "627" corresponds to our 24-637 sash balance. As for your middle window, our 24-1033 accommodates your "1031" sash balance. These balances don't come in left and right because you have equal heights of the top and bottom sash.
