Adjust 100 Series Casement Window Sash

A properly adjusted casement window sash will have an even reveal (the gap between the window sash and frame) when the window is opened one (1) inch from the side jamb (the pieces forming the sides of a window frame).

To adjust your 100 Series casement window sash, follow the directions in the Sash Adjustment Guide for Andersen 100 Series Casement Windows (9031737).

If adjusting the window sash does not resolve the concern, Contact Andersen® Windows and Doors for assistance.
