Product review (1 stars): The roller stud does not connect securely to the rack ...
The roller stud does not connect securely to the rack, allowing the stud and wheels to fall off when the rack is rolled in and out of the dishwasher.  The seller advertises a GE part number, but the item is not an OEM part, the design is different than what came new.  Save yourself the headache and stick with an OEM part.
