Spiral balance

Question

This spiral balance came out of a 3050 aluminum window. It's about 30 or 40 years old. It's single pane glass, and that's about it. Thank you, Scott

Hello,

If your balance measures 5/8" in diameter by 29" long for a non-tilt window, see the S500-29. Note that the red tips are calibrated for a sash between 7-29 lbs. Thanks for posting!
