Coil balance

Hello, thank you for posting,

Your coil balance resembles the 15-177 pivot shoe that is compatible with the Series 152 coil springs. Compare the dimensions below to confirm a good fit! The original springs should have a number stamped into the metal that indicates the weighted option needed. The original balance will need to be removed to check for numbers. 

If there are no markings, we will need to know weight of the window sash to move forward. Let us know if you have any questions!  

If new covers are needed, see the 15-143 bushing, 15-144 bushing cap and 15-145 support barrel.
