Replacement of window sash balance for Anderson window

A home owner from Swedesboro, NJ says:
Window is 30 years old. Approx. size is 36"x54".
One sash cord on lower sash, left side as looking out, is broken.
I need a window sash balance.
Also I need three window locks as shown in the attached photo.

For the Andersen sash balance box, we would need to know the unique stamped number on the box. There are going to be two sets of numbers, a 11600-17  type number and another set that's adjacent to it. We would need those second set of numbers in order to determine which replacement to recommend. Sometimes that number will include a letter or a # sign. As for your lock, start with taking a look at our 90-095 to see if this could work in place of your current lock.

Thank you very much.
I will get the numbers & then get back to you.

Good morning,
Please see the attached photo of the existing sash balance.
Can you confirm the model I need to order. I will need two of them for the same window, one on the left & one on the right.
Thank you,

Perfect! That's exactly what we needed to see, thank you. That 927 stamp tells us that you need our 24-939 Andersen sash balance. Please let us know if you need anything else!
