Do you sell this window curl spring?

Home Owner from Staten Island NY.
Hello: I need your expertise. I have a curl spring window that's broken. I took some photos of the broken side as well as the good side. The immediate problem is I took out the window for the photos and now I can't get it to go back in. Would you please, by the photos, recommend the replacement, and tell me the trick to get the window in it place. The jpeg photo 1392 is the broken sider. Thanks for your help.

Hello,

We can't be positive with your part still installed but the 15-180 is a good place to start. Take a look and compare the dimensions below to the original pivot shoe once you are able to remove it from the window. If it's a match, see the S180 coil springs and related parts shown on this page that work with this assembly. Thank you!

Casey: I dismantled the window Coil Spring casing. It looks like the double support detent # 15-181 matches the part in the photo. The Coil spring has a Number 5 stamped on it. From the photo how many springs do i need? Would you be able to supply a diagram as to how I can restall the new springs. And should I replace everything? Thanks for your help.

It looks like your balances use the 15-181 double support, which indicates that you'll need two coils for each side. See the S180-05 coils, which support 5 pounds each. We do not have a video showing this exact assembly but we've related multiple coil balance videos on this page to help you through the process.
