Window balance obsolete
Hello there. Can you tell us the diameter of the spring on this crossbow balance? That will help narrow down what you need.
Thanks! So, for full transparency, your old balance is strictly not made anymore. This is a very old, obsolete model.
However, over the years we've found a more modern balance style that can work in the same window with a little handiwork. It's not made to work in the window, but should be okay as long as you follow the steps listed in the video below. The balance in question is our Series 795.
Your next step should be to watch this video and buy the recommended products so that you can get this window functional again.
