2 Andersen window coil spring balancers

Question

I need two coil springs for my old Andersen windows... 36" wide and 34" high, 14 verticle inches of visible glass on each of the double hungs windows. Each box is 3" x 6 1/4" with a 1/2" metal lip. I removed them from two rectangular recesses located above the windows. The windows weigh 12# each.

Thank you for reaching out to us. I recommend you have a look at the 24-531. This Andersen balance is designed to replace those that include the 5#23 stamp. Take a look and let us know if you have any questions.
