This is one (Pic 1 and 2) of two spring balances for Schuco Corona 3050 double hung window (Pic 3).

Home Owner from Springfield NJ
I have a few windows with broken spring balance system. All my windows were installed in 2002. I'm unable to find replacement parts, since Schuco residential dept. no longer supports old windows.
I hope you may have info that will help me order replacement parts
Thank you

Thank you for contacting us! Take a look at the 15-087. This is designed to be used with the Series 180 (sold separately). Review the specifications and see what you think. You'll also have to weigh the window sash and divide the sash weight by the total number of springs in the window to determine the proper spring weights. 

Please let us know if you have any questions!
