Single Pane Balancer 4R

Hello,

Your part resembles the S140-4 but we would need to see the entire balance assembly removed from the window to confirm if it will work for your repair. Thank you! 

Thanks for getting back to us. Your photo does look like a match to the S140-4 coil balance shown below. You'll see options to indicate the left and right-handed versions of this balance on our product page.
