Old simonton constant force sash balance

Hey there,

Thanks for writing in! Your Simonton balance assembly is no longer made but the 15-259 Coil Balance Shoe should work well to replace it. The existing pivot bar will not be compatible, so you'll also need the 26-083. The specifications for these parts can be found on the website. Be sure to compare the specifications to ensure they'll be a fit.

This shoe uses the Series 159 Coil Balance. To determine the correct coil weight option, you'll need to confirm the exact weight of the window sash. Please see the tutorial (tagged below this thread) for instructions on how to determine the weight option(s) you need.

For the coil support, take a look at the 15-255 Coil Single Support.
