Hello,
Can you please identify this part? The window shuts on itself and I believe this will need to be replaced. Thank you.

Hello, thank you for posting,

Please start by reviewing the style and dimensions of the Series 140 coil balance. Based on the 6R stamp, see the S140-06 coil balance. This balance will give you 6 pounds of support, together with the other side the total sash weight should be 12 pounds.

Compare below to confirm a good fit and let us know if you have any additional questions!
