Tilt window balancer

Hello! Looks like you need a new coil balance assembly. I recommend our 15-180 pivot shoe, 15-186 clip and 15-182 bushing, and our Series 190 spring. These parts all appear to match the hardware in your photos, but let me know if you had any questions.

There should be a stamp on the original coil band that you can reference. If you can't find that, or if it's too faded to read, then you can weigh your sash on a scale and tell me what you get. I can then calculate the proper strength option.
