Milgard Window Balancer

Hello,

We'd be happy to help but we'll need a bit more information to get started. If you could show us the connecting point between the spring and pulley inside the metal channel, that will help us confirm if your balances need to be custom-ordered or if our stock balances would work for your window. Thank you! 

With this combination of attachments, you could have either the S380-24 or S385-24 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. 

You'll also need 2340 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
