Window coil spring

Hello,

We'd be happy to help but, unfortunately, the stamp only indicates the strength of the spring. To identify the correct replacement, we'll need to see photos of your balance removed from the window, please make sure to include both end fittings and the connecting point between the spring and pulley inside the metal channel. That would help us confirm if our stock balances could work for your repair or if they would need to be special ordered. Thank you!
