Window Pivot Shoe

Thanks for posting! This coil balance assembly reminds me of the 15-087 Coil Housing Pivot and 15-086 Tandem Coil Housing.

Detail of 15-087

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. We use a different assembly in the video but the process would be the same.
