Double window balances were broken

Hello, thank you for posting,

Your coil housing pivot resembles the 15-087 that is compatible with the Series 180 coil springs. Please review the overall dimensions below to confirm a good fit! 

There should be a number stamped into the metal coil that indicates the weighted coil needed, but if not, please provide the weight of the window sash to move forward. The window sash will need to be removed and placed on a bathroom scale.
