My window sash weight is 17.8 lbs. One side spring is broken. The shoe looks like your S140-10. I am not sure if I need to buy S140-10. The spring is single, its width is 11.8mm (0.464").
The shoe width is 1.25", 0.5" thick. Please help.
which part should I choose?

Hello! I agree, our Series 140 looks like a great match. Since the stamp on your old cover is 10 then the S140-10 would be my pick, as well. You can always weigh your sash on a scale to confirm.
