Anderson Window balance replacement needed. numbers on the box stating BP6 12R 10-8. The 10-8 is hard to see on the box, unsure if there is anything after the 8.

Not sure if these are right vs left? Or universal.

Hello!

For your right and left balance, we recommend 24-13L for the 12L stamped balance box and 24-13R for the 12R stamped balance box. Take a look and see what you think.
