A self-rimming vent, also called a drop-in vent or surface mount vent, is one that sits on the surface of an installed floor. It simply drops into an opening cut in the existing floor and is a preferred style for most flooring surfaces. It can be used with new or existing hardwood flooring, laminate, carpet, tile, or vinyl, with the rim of the vent neatly concealing the cut edge of the finish flooring. It frames the floor much like metal vents and adds a perfectly finished touch to any floor covering. This vent is not recommended for use in traffic areas.
