constant force coil balance needed

Question

Hello,
I am looking to replace the coil balance assemblies for a window.

shoe width ; 1.25
shoe depth ; .5
coil spring thickness ; .5
8lb spring rating.

There appear to be two coils in the assembly, but I am unsure if this is a single coil that snapped or if I must replace both. Thank you in advance for the help!

This balance shoe is a match for the 15-180 Coil Balance Shoe. I'm confident this is the correct replacement but be sure to double check the dimensions.

This shoe uses the Series 190 Coil Balance. It is attached using the 33-073 screw. You'll need the S190-840 8lb coil for the repair.

The pieces anchoring the coils to the window jamb are the 15-186 Coil Balance Clip and 15-182 Balance Bushing.
