Broken coil balance

A home owner from Atlanta GA says:
Please help to select the parts to order to replace the broken coil balance and pivot shoe.
The coil width is 0.5 in, the sash weight is 20 Lb.
Thanks,
Anatoliy.

First, take a look at our 15-175 shoe and let me know if the specs match your own. If so, I recommend that you consider our S152-5 coil spring.
A home owner says:
Thank you.
May I use a single coil spring S152-9 instead of double coil spring S152-5?

Paul from SWISCO responded:
S152-9 is going to fall short of 20 Lbs. Since the manufacturer uses two springs, I would stay with two S152-5.

Thank you, appreciate your help.
