Coil Balancer - 6 or 9

Thanks for reaching out! I believe the stamp on the coil could be a 6 but to be sure, I would recommend obtaining the exact weight of your window. The 6 and the 9 is, unfortunately, one of the stamps that is not immediately obvious. The stamp orientation changes all the time so the best way to know is the get the window window.

Once you've obtained the window weight you'll need to divide that number by the number of coils to confirm the exact coil spring you'll need.
