Hello, I'd like to replace both left and right balance springs as one side is broken. A contractor installed this tilt-out window about 8 years ago.There is a Lowes sticker on the bottom but no other manufacturer information. Can you identify the type of spring mechanism from the parts in the photos? Thanks, Wayne

Hello,

I would recommend removing your coil balance assembly from the window to compare to the 15-087 housing pivot, S180 coil springs, as well as the parts listed under the related items section of each product page. Thanks for posting!
