Could I get help with a replacement part? The window was made in October 2006

Hello, thank you for posting,

Please review the 15-199 pivot shoe to confirm a good fit!

Alternate view of 15-199

Is the thickness of the coil springs, 3/8"? If so, please see the Series 165. For a coil marked 4.0, see the S165-4 coil balance along with the 15-205 triple support cover.

Together with the other side, this configuration of coils will support a 24 pound window sash. Please review and let us know if you have any additional questions!
