Coil balance

Hello, thank you for posting,

Please review the style of the 15-087 pivot shoe that is compatible with the Series 180 coil springs along with the 16-024 bracket. Review all dimensions to confirm a good fit! Based on the (4) marked on the pivot shoe, see the S180-04 coil spring. 

Together with the other side, the sash should weigh 8 pounds. 

Let us know if you have any questions!

We do not have a specific video on this balance assembly, but see the diagram below for assistance disregarding the tandem housing as your original does not use one.
