window springs

Hello,

It sounds like you may be looking for replacement support balances that support the weight of the window sash. We may be able to help but we would need to see your assembly uninstalled to compare to our inventory. We'll relate a few videos on this page to assist you depending on the type of windows and hardware that you have. Thank you! 

Thanks for getting back to us! Your pivot shoe resembles the 15-111 , which uses the Series 160 coil springs. I would recommend removing your coil balance from the window to confirm that the specifications match our replacement parts. There should also be numbers stamped on the based of the coil springs that you'll need to choose the corresponding strength options.

We're happy to help but your stamp is a bit out of the ordinary. Could you show us a photo of the stamp code on your coil spring? 

Great, the 4.5 stamp indicates that you would need the S160-4 coil springs. Take a look and let us know if you have any other questions.
