Non tilt spiral window balance

Unfortunately, we are no longer able to provide replacement balances with that same metal hook at the bottom. We recently discontinued it. There is no confirmed substitute at the moment, either; due to the public health crisis, we have not had the opportunity to experiment with different options.

However one possible substitute could be the Series 400 along with a new 17-031 bracket, which would cradle the sash from underneath. It would require drilling a new hole and using a #8 screw. I cannot guarantee that it will work well, or if it's even possible, but we don't have anything else to suggest at this time. I apologize for the inconvenience.
