Constant Force Balance Blue Cam #6

Hello, thank you for posting,

Your balance assembly resembles the 15-087 pivot housing that is compatible with the Series 180 coil springs. Please review the overall style and dimensions to confirm a good fit! Since the housing is stamped with the #6, review the S180-6 coil spring. Please review and let us know if you have any additional questions!
