This Andersen replacement Sash/Counter Balancer is used on Narroline Double-hung windows manufactured from 1968 to 2012.
Balancers are used to maintain the position of the window sash.
They are found above the upper sash in the head jamb, and are located on each side of the window.
When replacing a balancer, we recommend replacing both balancers and the window side jamb liners.

Please double check all requirements.
1. Andersen 200 Series Narroline Double-Hung
2. Measure Lower sash exposed glass. (all visible glass on the Lower sash)

NOTE:
Each window uses two balancers.
The same balancer is used on both the left and right hand side of the window.
