A flush mount vent grille in the Carbonized strand bamboo color is designed to complement your new floor. Functionally it covers a central air duct in a way that allows it to sit flush with your new floor but with a removable center piece. You can walk on it just as you would the rest of the floor because it has the same wear resistant finish as our flooring. Please note the dimensions in the images above and plan accordingly as you install. We also carry this vent in another, slightly smaller 4 inch by 10 inch size here.
