Upgrade balancer

Thanks for reaching out! The window balance you have is either the 5/8" (also considered 9/16") Series 600 Spiral Balance or the 3/8" Series 900 Spiral Balance. To determine the correct replacement, you'll need to measure the length of an undamaged balance and confirm the diameter of the tube.

Take a look at the video tutorials below for instructions on how to remove/install the balances and how to identify them. There are also videos detailing how to remove/install the pivot shoes.
