We have windows with 11600-17. Other numbers stamped on each balancer are "11L 3" and "BU 12 1190." Any ideas? Thanks!

Based on what you've described, we believe you have cottage windows, where the top and bottom sashes are different sizes. I think you might need our 24-11R and 24-11L Andersen balances, but to be sure I'd like you to tell me the width" x height" of the visible glass for both the top and bottom sashes. |
