Triple coil balancer

Thanks for posting. This looks like it might be the 15-228 Pivot Shoe. This shoe works with either 1/2" thick Series 160 Coil Balance springs, or the 3/8" thick Series 165 springs. You'll need to remove your old springs and measure the thickness of them to determine which you need. The video below shows how to remove and replace a similar Coil Balance assembly. Let me know if you have further questions.
