The Whirlpool WPW10740410 Dishwasher Dishrack Adjuster is an authentic genuine replacement element which enables you to change the vertical position of the upper dishrack in your Whirlpool dishwasher. This adjuster is frequently constructed out of a gear mechanism or a sliding track system that links to the dishwasher's frame and the upper rack itself. You may modify the mechanism to raise or lower the upper rack to make additional space for tall dishes or pots on the lower rack, or to better fit smaller bowls and cups on the upper rack. This enhanced adaptability indicates that you take the most use of your dishwasher's space and are capable of cleaning dishes of all shapes and sizes.
