Abstract: A dish rack is supported for both selective movement into and out of a washing chamber of a dishwasher tub and vertically relative to the tub, with the vertical adjustment being made by manually grasping and shifting at least one frontal cross bar extending above a front wall of the dish rack to cause pivoting of first and second lever members extending along sides of the dish rack. The side lever members cooperate with latching mechanisms to lift and retain the dish rack in a select raised position.
