Replacement Pivot Shoe

Thanks for reaching out to us! I believe a better replacement match for your Simonton shoe would be the 15-259 Coil Balance Pivot Shoe. Take a look over the dimensions below to determine if this will fit in your window channel.

Dimensions for 15-259

This shoe is compatible with the Series 159 Coil Balance. You'll need to look for any stamps/markings on your existing coils to select the springs you need for your assembly. If there are none, you'll need to obtain the exact weight of your sash and divide it by the total number of coils in the window; in your case, (4).

You'll likely also need the 15-256 Coil Double Support (for the coils) and the 26-083 Pivot Bar, since your existing pivot bar is very likely to be incompatible with the 15-259 shoe.

Yes, the S159-10 would work fine, especially since when divided the weight comes out to 10.9lbs and 10.4lbs respectively. You'll need the 15-255 Single Support instead.
