Two sets of feet come in the box: four wheels if the cabinet should roll out for cleaning, four adjustable pads if it should stay put on an uneven floor. Five tiers behind four flip-up PC doors that open upward where a swing has no room. Guardrails stop items sliding off, four hooks hang off the frame, and a heavy-duty metal structure carries forty-five pounds a level.
