Replacement of window sash balance for Anderson window

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.

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!
