Casement window hinge with reduced sash-sag

摘要

A casement window hinge protects against sash sag by providing a guide arm that substantially fills the space between the sash and the window frame when the window is closed. This space-filling guide arm may be produced with lightweight thermoplastic material whose pivoting connection to the sash arm may be strengthened through a wood screw providing an axis for the pivot that may be stabilized within the sash into which the screw is driven.
