Window balance replacement ID

Hey there,

Thanks for reaching out to us! Your coil balance assembly is no longer made but the 15-177 Coil Balance Shoe will work to replace the shoe. I'm confident this will work for the repair but be sure to compare the dimensions.

If you need a replacement for the pivot bar, I'll need to see a photo of it removed from the bottom of the window.

The compatible coil spring is the Series 152 balance, attached to the shoe using the 33-072 screw. Since the sash weighs 17lbs, you'll need either the S152-8 (provides 16lbs of support) or the S152-9 (provides 18lbs of support).

The support can be replaced with the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel.
