Replacement sash balance

Question

I'm looking for a replacement Anderson window sash balance for left and right. I have included a picture of the left balance. Can you help me with a part number? My windows were installed in 1987.ish. The numbers i can read are 11600-17 and T1 16L 6-86
Thanks!

Hi Sandra. I can see the code "16L" printed on one of your balances, which tells me that that would be replaced by our 24-16L . This goes on the left side, while you would need the 24-16R for the right side.

Please let me know if you had any questions.
