Certainteed Double Hung Windows ~ Coiled Balance Spring Replacement

A quick learner from New York says:
Trying to figure out which series # will be the proper replacement for broken coiled balance springs for my windows. Springs on both sides have snapped. The pivot shoe # reads A186160 if that helps.
Can you please help me ~ thank you!

We appreciate you contacting us with your hardware needs. Starting with your pivot shoe, see if our 15-192 is a good match. These are used with the Series 170 coil springs. See if you should have any stamped numbers on your spring. If so, get back to us with that information. If not, let us know the weight of your window sash and we will go from there.
