Outside: a clean slot profile that looks more refined than a bulky stamped grille. Sizing Guide — Will a 14x2 fit your space? IMPORTANT: Measure the hole in your wall, ceiling, or floor — do not measure your old vent cover. This 14x2 aluminum vent cover is designed to fit a standard 14" × 2" duct opening (also listed as a 2x14 wall register or 2 x 14 vent cover). Duct opening size: 14" × 2" (this is what you measure) Neck size: 13-3/4" × 1-3/4" Overall face size: 15-3/4" × 3-3/4" Design note: Like all linear slot diffusers, this model has a narrower face panel than many traditional louvered grilles to achieve a cleaner, minimal aesthetic. It may not fully conceal the unpainted area left by an old AC vent cover — a light paint touch-up may be needed for a perfectly finished look. Quick check: Remove your existing vent cover. Measure the opening in the wall, ceiling, or floor — not the old cover. If the opening is approximately 14" × 2", this 14x2 linear slot diffuser fits. Designed for modern homes The 14x2 size is designed for extra-long slim openings where the vent should read as a thin architectural line. It is a strong fit for soffits, narrow ceiling runs, modern hallways, and accent-wall applications where the finish matters as much as the function. On the wall Replaces dated stamped-steel grilles in soffits, narrow ceiling runs, modern hallways, and accent-wall applications. The clean slot line helps the HVAC opening blend into the room instead of becoming a visual distraction. On the ceiling Creates a low-profile look for finished ceilings, modern condos, kitchens, bathrooms, and basements. Use the included screws for a secure wall or ceiling installation. On the floor Works in low-traffic floor areas where a modern register-style look is preferred. For busy walkways or heavy foot traffic, choose a heavier-duty floor register. Premium Features Alloy aluminum construction: A heavy-gauge aluminum body with no plastic parts helps resist rust, warping, yellowing, and everyday wear. Clean architectural finish: The powder-coated face wipes clean easily and gives walls, ceilings, or floors a sharper modern profile. Adjustable airflow control: The built-in adjustment bar lets you direct airflow left, right, both ways, or fully closed for unused rooms. Quiet slot geometry: Wider slot spacing helps air move at a controlled velocity, reducing the harsh whistle often heard from narrow-slot covers. Built for Everyday Residential Use: Designed and crafted in Vietnam with attention to finish quality, durability, and practical usability for U.S. homeowners and contractors. 5-Minute Retrofit Installation Designed as a direct replacement for standard 14" × 2" duct openings with no structural modification required. On Walls & Ceilings: Mounts with the included screws through pre-drilled hidden side holes. Only a screwdriver and the included adjustment tool are needed. On Floors: Drop the cover into the existing opening in low-traffic areas. Optional screws may be used for extra hold. Fully Removable: The diffuser can be removed for cleaning, painting, maintenance, or future room updates.

What size do I order — 14x2 or face size? Order by duct opening size. 14x2 means a 14" × 2" duct opening—the hole in your wall, ceiling, or floor. The visible face size of this diffuser is 15-3/4" × 3-3/4". 2. Is a linear slot diffuser better for modern interiors? For contemporary rooms, yes. The straight slot profile looks cleaner than stamped louvers and pairs well with minimalist walls, ceilings, hardwood floors, and modern trim details. 3. Can I install this 14x2 vent cover on a ceiling? Yes. This 14x2 linear slot diffuser can be installed on walls, ceilings, or low-traffic floors as long as the duct opening measures 14" × 2". Use the included screws for wall and ceiling installation. 4. Does it include an adjustable airflow damper? Yes. The built-in adjustment bar lets you direct airflow left, right, evenly to both sides, or fully close the blades to reduce airflow into unused rooms. 5. Can this diffuser be used for both supply and return air? It can be used for supply air and many residential return openings. For high-volume returns or filtration needs, choose a dedicated Green Vent air return grille with pre-filter instead. 6. Can I use a filter with this linear slot diffuser? No. Standard filters should not be placed behind individual vent covers because they can restrict airflow and strain the HVAC system. Use a return grille with a pre-filter if filtration at the vent is required. 7. Is the finish paintable? Yes. The powder-coated finish is durable as shipped, but it can be lightly sanded, primed, and painted with standard spray paint for custom color matching. 8. Can this be installed outdoors? Yes, in sheltered locations such as covered patios, garages, and enclosed porches. It is not intended for direct rain exposure.
