Abstract
A vertically adjustable lower hinge assembly for a center-hung door, such as for use on a refrigerator or freezer. The lower hinge assembly is adjustably fastened to the door frame. Beneath the lower hinge assembly is an adjustable support member in the form of a cam plate that is also fastened to the door frame. The support member is used for raising or lowering the lower hinge assembly, and in turn changing the elevation of the door. The support member also reinforces the holding power of the fasteners of the lower hinge assembly.
