Which coil balancer?

A quick learner from East Norriton, PA says:
Both balancers broke and are 1/2 inch wide. There are no labels on the coil and the window weighs 11 lbs. What coil do you think I need?

I would go with our S152-6 coil spring. This looks to be a good match. These are 1/2" wide and having one on each side can carry the weight of your sash no problem.
