2004 Milgard Window

Question

I'm trying to identify my Milgard window springs. House was built in 2004. The length of the metal part of the spring is 33 inches. Can you help identify a replacement? I have attached photos.

Thank you,

Rod

Hi Rod, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 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 will need a 33" balance with a 3240 stamp option. Please review and let us know if you have any additional questions.
