**SIMILAR**Vent Cover Black Metal Adjustable Foundation Vent Crawl Space Louvered

This 16x8 black metal vent cover is an adjustable steel grille for finishing a wall, ceiling or foundation opening. The outer frame measures 15.75 x 7.87 in (400 x 200 mm) and it suits openings up to 14.9 x 7 in. The screw holes are spaced 15.28 x 7.40 in and the frame is only 0.24 in thick, so it sits tight against the surface. Behind the louvers a manual regulator lets you open, reduce or close the airflow, which makes the same grille usable for supply air, return air, fresh air intake or exhaust. You set the airflow once for the room and leave it, or close it for the cold season on a crawl space or foundation opening. The grille is made of galvanized steel with a black polymer coating. It resists rust, fading and knocks, works indoors and outdoors, and stays rigid and quiet where thin stamped metal or plastic covers tend to rattle. The black finish suits dark siding, brick and modern interiors. Mounting is simple: hold the frame over the opening, mark the pre-stamped holes and fasten it to drywall, wood, siding or masonry. Screws are not included, because the right screw depends on your surface. Typical uses are a return air grille, a wall or ceiling register cover, a foundation or crawl space vent cover, and ventilation for a garage, basement, workshop or utility room. Before you order, measure the opening itself, not the old cover, and make sure it is smaller than the outer frame on every side.
