Thanks for posting. I believe Andersen Narrowline windows use our 24-837 for "2452" and 24-1133 for for "3052." However, if you want to be sure, you will need to remove the balances in question from the window and show us a few pictures of the stamps printed on the boxes themselves. This will allow us to confirm what can work.
