27" Spring Balancer replacement x 2 needed

Question

Dear Manager,

I'd like to purchase two spring balancer for my Milgard window. Attached please find two pictures for the top and two pictures for the bottom, as well as a view for the whole balancer that has "26 4 GW CMC 7" printed on the aluminum tube.

Thanks so much!

Hi Sunny, 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 27" balance with a 2640 stamp option.

Please review and let us know if you have any additional questions.
