Part size 2 15/16 inch by 1 3/16 inch, not including shoe part in photo.
I need two constant force window balances including shoe and coil springs.
Window manufacturer is Hayfield Windows, Double Hung Window #800
Part # on photo is 801020
Window weight is 24 lbs., so need to support 12 lbs. on each side.
Again, I need parts including shoe and coil springs, for both sides of window.
