This is a popular optional piece of trim when the NR-751 refrigerator/freezer is installed in a raised enclosure (similar to how galley stoves are typically installed). See Related Products, below.
The NR-751 refrigerator has a cooling air intake that is recessed about 2" from the face of the fridge. You can see the recessed vent grill in the refrigerator images.
If you are mounting the refrigerator on the floor/cabin sole, you probably do not need this trim piece.
However, if your installation is in a raised enclosure, chances are once your installation is complete you will still be able to see the rough cut-out along the bottom edge of the enclosure - due to the recessed vent grill.
This trim piece lies flat, horizontally, over the lower edge of the enclosure and covers that rough edge.
Unlike the rest of the cosmetic framing, this piece does not come with the refrigerator.
Currently only available in black.
