Abstract
A hinge assembly for a casement window including a track having a cam engaging portion defining a tri-lobular aperture, a sash arm pivotably and slidably coupled to the track, and a support arm pivotably coupled to the track on a first end and to the sash arm at the opposing end. An adjustable cam is operably connected through the support arm to engage the non-circular aperture within the track such that rotation of the adjustable cam selectively shifts the position of the support arm relative to the track to alleviate sash sag.
