Tilt Window Balancer

I have what look like galvanized window balancers without any identifying numbers or markings. No colored tips to identify weight either. They are 3/8" x 35" and the vinyl window weighs 20.12 lbs. Your help would be greatly appreciated in identifying the correct replacement window balancers.

Looks like you need tilt window spiral balances. Based on your dimensions and sash weight, you want the S900-35 with a Green Tip color option.
