Vinyl Windows Reel/coil balance replacement

A home owner from New Jersey, USA says:
Hello!

I have couple Vinyl Windows are not able to stay opened safely, upon researching on the internet, some of these coils are broken. I can't seem to find a replacement. Your product S140-6 seems to be the closing product I can try. Do you have the exact measurement? I wanted to see if they are the same size before I try them.
I was not able to find the model or factory from the window. There is a number "5R" on the coil tension, I guess that's for the weight it supports?
Thank you for any advice.
Jack

Hello,

I agree that your coil balance resembles the S140 but the 5R stamp on your assembly indicates that you would need the S140-5. See the dimensions below to compare to your balance shoe. Thanks for posting!
