This system is perfect for installing in a cabinet to draw cooler air into the cabinet from the toe kick making the installation virtually invisible. The Cabinet Vent easily installs in the base (bottom) of the cabinet and the rectangular grill in the toe kick. This way, air is pulled through the toe kick and directly into the cabinet. This system can be easily installed either when the cabinet is in place or during the construction of the cabinet.This package includes one self-contained Cabinet Vent fan unit, a power supply, and a low profile toe kick vent grill. The toe kick grills are available in black and white plastic or maple, oak, and teak wood.
