Coil balance

Hello, thank you for posting,

Your pivot shoe resembles an older version of the 15-180 that is compatible with the Series 190 coil springs. Please review the dimensions below to confirm a good fit! 

Alternate image for 15-180

The original coil springs should have a number stamped on each coil that indicates the weighted option needed. If there are no markings, please provide the weight of the sash to move forward.

Also see the 15-181 double support and 15-182 balance bushing. Let us know if you have any additional questions!
