Milgard Window Balancer Strings Broken

Question

Hi, I'm looking to replace a broken Milgard window balancer in my home. The steal part of the balancer is 39 inches long. The window itself is 39inches wide and 41 inches long. The cord has snapped on the one side of the window and I am looking to replace the entire balancer. I had attached pictures

Thank

Hello,

With this combination of attachments, you could have either an S380-39 or S385-39 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 to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.

Thank you and let us know if you have any other questions or concerns.
