I need a replacement sash balance for a double hung Andersen window that is 34" wide, 54" length. The markings on the sash balance we have currently are 11600-17 on the body of the unit and 827 K78 1153 on the "lip" of the unit by the staple.

Hello,

The (827) stamp on your balance indicates that you could use our 24-837 Andersen sash balance as a replacement. Thank you!
