Heavy-duty stamped 304 stainless steel midget vents feature a reinforced rim making them durable enough to stand on. Great for routing cables or wires through a hole or for covering thru-hull openings to shield water spray. Ideal for small lockers, they provide attractive cover for ventilation holes while also preventing odors. Three pre-drilled holes for a smooth screw on installation. #6 RH fasteners not included.
