window balance for simonton single hung

Question

Hello, I have a simonton single hung window with the sash weighing 19lbs. Windows are about 16 years old. I have multiple window balances that are broken. I was hoping you would be able to help me identify the replacement. Attached are pictures of the balance and coil numbers. There were not unfortunately any numbers on the balance cover. Each balance had 3 of these coils in the pictures. Please let me know what other identifying information you may need to help figure out a replacement. Thank you so much for your help

Thanks for reaching out! You pivot shoe appears to be our 15-199. To confirm that this is the replacement you'll need, you may need to remove them from the window to properly compare the measurements.

These are typically compatible with our Series 160 and Series 165 Coil Springs. Although, since your is stamped with a #4.0, I am assuming you'll need the S165-4. Confirm that your coil spring is 3/8" thick to determine that this is the correct series for your coil balance assembly.

You'll need to check the other coils for the stamps to confirm which coil balance springs are the best replacement.
