Enhance airflow with sleek and durable linear grilles, perfect for modern ventilation solutions. Ideal as vent covers, air diffusers, and HVAC registers for walls, ceilings, and floors. Upgrade your space with high-quality linear air vent covers designed for efficient air distribution and a seamless aesthetic.
OKUN linear grilles are designed in New York City for residential and commercial spaces that want architectural detail without commercial pricing. Rust-resistant aluminum, matte white finish, and a concealed-mount design with no visible screws on the finished face. Designed for supply air, with adjustable blades to direct and control airflow, and engineered for both walls and ceilings. Available in 6 sizes from a 10" x 4" duct opening up to 30" x 6", priced from $40.90.
OKUN linear grilles use a concealed-mount design with hidden fasteners on the finished face, so no screws are visible, unlike traditional stamped-metal builder-grade vent covers. All OKUN grilles are designed in New York City, constructed from rust-resistant aluminum with a fade-resistant matte white finish, fitted with adjustable airflow blades, and engineered for both ceiling and wall installation in residential and commercial spaces.
An OKUN linear grille is an elongated, narrow slot diffuser designed for long architectural runs and modern feature lines. Standard grilles are rectangular vents sized to fit common residential duct openings. Square grilles are proportional square-format vents for evenly proportioned ceiling or wall installations. All three lines share the same concealed-mount construction, aluminum build, and matte white finish; the difference is shape and proportion.
Measure the duct opening, the actual hole cut into the ceiling or wall, not the existing vent cover's outer frame. OKUN linear grilles are sized by duct opening, and the front face is approximately 2 inches larger in each dimension to overlap the surrounding surface. If the existing vent has been painted over or shimmed, measure the actual cutout before ordering.
OKUN offers 6 linear grille sizes by duct opening: 10x4, 12x4, 14x4, 16x4, 20x6, and 30x6 inches. The front face on every size is approximately 2 inches larger in each dimension to allow flush coverage of the cutout.
Yes. All OKUN linear grilles are designed for both ceiling and wall installation. The concealed-mount design lets the grille sit flush against either surface with no visible screws. Floor installation is not recommended because the linear slot configuration is not engineered to support foot traffic.
A vent register has adjustable horizontal blades or dampers that can be opened, closed, or tilted to control airflow direction and volume. A vent grille is the broader category that includes both fixed grilles and adjustable registers. OKUN linear grilles include adjustable horizontal blades behind the slot opening, so the terms grille and register describe the same product: an airflow-controlling vent cover with concealed mounting.
OKUN linear grilles are supply-air grilles, designed to direct warm or cool conditioned air into a room. The adjustable horizontal blades let you aim the airflow, balance it between rooms, or restrict it as needed. Because the blades control direction and volume, they make a clean, modern replacement for supply registers throughout a home.
An OKUN linear grille installs over an existing duct opening using the included mounting hardware and a standard Phillips-head screwdriver. The concealed-mount design hides the fasteners behind the grille face, so no screws are visible. Installation typically takes under 10 minutes per grille and requires no specialized tools, no duct modification, and no professional HVAC work when replacing an existing vent of the same duct opening size.
OKUN standard grilles are constructed from commercial-grade aluminum, not stamped steel. Aluminum does not rust — important because vents experience condensation from temperature differences between conditioned air and the surrounding surface. Standard steel vent covers can rust over time, especially in humid environments like bathrooms and kitchens or near AC supply runs. Aluminum also holds its matte white finish more durably than steel, resisting yellowing and chipping over years of use.
Yes. OKUN linear grilles include adjustable horizontal blades behind the slot opening that can be tilted to direct or restrict airflow, or shut it off entirely. The blades adjust with any standard household tool, such as a flathead screwdriver or a coin, making airflow tuning a simple DIY task. This is especially useful for supply vents: balancing room temperatures and redirecting conditioned air away from seating areas.
OKUN linear grilles are priced based on size, starting at $40.90 for a 10x4 duct opening and increasing with larger dimensions. Builder-grade stamped steel vent covers typically run $10 to $20 but tend to rust over time and show visible mounting screws, while architectural-grade custom diffusers often cost $100 or more per grille.
OKUN standard grilles offer concealed-mount construction, rust-resistant aluminum, and a matte white finish at a price point between builder-grade vent covers (stamped steel, visible screws, $10 to $20) and architectural-grade custom commercial grilles ($100 or more). OKUN is designed in New York City for residential and light commercial use, with 20+ standard sizes that fit common residential duct openings — eliminating the custom sizing and commercial pricing typical of pure architectural brands.
