Certainteed window with coil springs
Thanks for reaching out to us! The shoe in this coil assembly can be replaced with the 15-180 Coil Balance Shoe. While I am confident this is the correct replacement, it is encouraged to compare the dimensions and confirm it will be a fit.
This shoe is compatible with the Series 190 Coil Balance, which is attached to it using the 33-073 screw. To determine which coils are needed for your assembly, you'll need to remove them and check for any stamps/markings. Please see the video tutorial tagged below for a more detailed explanation on selecting the coils.
You may also need the 15-181 Double Support Detent Clip and two of the 15-182 Balance Bushings for the repair.
