Having trouble with this part from an Andersen double hung window
The numbers that look important are D13 7 #27 11 80
It also is stamped 11600-2 on one side and 11600-3 on the reverse side
This one is a right hand unit

Hello there. See the 24-737. This will replace old Andersen balances with the stamp 7#27, or 727. Let us know if you have further questions.
