VINYL WINDOW BALANCE

Thanks for posting! The pivot shoe you are searching for looks a lot like the 15-180 coil balance shoe. Look over the dimensions and compare them to your existing shoe to confirm that this is the right fit.

These shoes are compatible with the Series 190 coil balance spring. To choose the coil spring needed for your assembly, check the metal spring for a stamp that will indicate the spring strength you'll need to chose from the Series 190 coils. 

If there are no stamps, you'll need to obtain the exact window weight and divide it by the total number of coils in the window.
