Broken spring

Thanks for posting! This coil balance assembly reminds me of the 15-087 Coil Housing Pivot and 15-086 Tandem Coil Housing. The dimensions for them can be viewed on the website.

These are both compatible with the Series 180 Coil Balance. To determine the correct coils for the replacements, you'll need to look for a stamp/marking on the existing coils. This number represents the amount of weight the coil can support. If there are none, please see the tutorial below for instructions on selecting the correct coil weight option.
