A hinge and track assembly for casement windows corrects for sash sag by changing the length of one arm in a multiple lever arm system controlling the opening of the window. The length adjustment may be accomplished with an expansion joint removed from the pivot points of the arm permitting the use of a more robust design for one pivot point which may be integrally formed with the track. The arm may be retained on the integral pivot point with a spring clip fitting within the pivot and providing inwardly flexing detents. |
