Window balance

Question

I need two of these window balances. I don't know much about them but they say 6k of the copper piece.

Hello, thank you for posting,

Your pivot shoe resembles the 15-177 that is compatible with the Series 152 coil springs. If the coil spring is marked with the number 6, take a look at the S152-6. Please review the overall dimensions to confirm a good fit and let us know if you have any additional questions.
