In one or more implementations, a notch is cut along the upper edge of a cabinet toe kick to allow ambient air to enter and exit an air cavity disposed behind the toe kick. A fence or trim piece is then installed in front of the notch to hide the notch from view and to create a labyrinth vent allowing ambient air to enter and exit the air cavity. This ambient air flow is required for proper operation of appliances requiring ventilation.
