Abstract: There is disclosed a cornering device for a garment support structure which includes first and second horizontal transverse assemblies. The cornering device includes first and second horizontal support elements, each having a first and second end. Also included is hardware for suspending the first ends of both elongate horizontal elements from their corresponding transverse assembly and parallel thereto, such that the second ends of both elongate support elements comprise an acute angle. Further included are means for mutually securing both second ends of the elongate elements and, concurrently, suspending both second ends at vertical offset in a desired plane beneath the plane of said transverse assemblies.
