The "34#" may indicate sash weight, but you really should remove the sash and weigh it to be sure. We have a chart on the S351-27 store page that lists each option and how much weight they can support.
As for the window that is missing its balances, do you at least know the Series? Is it also the Series 351 channel balance? If so, tell me the height of the visible glass and I can calculate what length you need from there. You will also need to weigh that sash so that you choose the correct option. |
