Hello, thanks for posting! It looks like you will need our S395-29. To determine the spring strength option, locate the stamp or imprint on your balance. If there are no markings, you can weigh your window sash and consult the chart on the product page. Good luck with your repair, and as always please let us know if you have any further questions!

I came to the conclusion that I need the S395-28 since I was measuring wrong. I need the 2740 as my sash is 22 pounds.
It is not in stock, how quickly do items come back in stock? I actually have 2 or 3 more windows with the same issue but I haven't measured those yet. I would like to place a single order and fix all of my broken windows.

Unfortunately, due to the COVID 19 pandemic, we have had a very difficult time getting restock ETAs from our vendors, a lot of whom are not operating at full capacity. The balances that you are inquiring about have been ordered but, due to the state of affairs, things have been moving a bit slower than we'd normally expect and our information is limited. We apologize for the inconvenience and appreciate your patience.
