- FITS 12X6 DUCT OPENING - MEASURE THE HOLE, NOT YOUR OLD COVER: This vent cover fits a 12" × 6" duct opening in your wall, ceiling, or floor. Measure the open duct hole only, not your old cover face. Important: the face panel of this linear slot diffuser is narrower than a traditional louvered grille, so it may not fully hide the paint-free area left by your old vent. A light paint touch-up is recommended for a clean finish. Still unsure about sizing? See the diagram in our photos. Fits standard residential and light commercial HVAC duct openings. FREE returns if sizing is incorrect - GREEN VENT support is available before you order.
- SLIM DESIGN - FITS SHALLOW DUCTS WHERE STANDARD DIFFUSERS WON'T: Standard linear slot diffusers have a tall neck that requires enough depth inside the duct cavity to fit. If your duct opening is shallow - common in thin walls, low-depth ceilings, or older homes with short duct runs - a full-depth diffuser simply will not go in. The GREEN VENT Slim Design has a neck depth of only 1-1/4" from the face surface - specifically engineered for shallow duct cavities where competing models cannot fit. Same clean linear slot look, same adjustable airflow - just built to go where others cannot. Made in Vietnam from alloy aluminum - no plastic parts.
- PREMIUM LINEAR SLOT DESIGN - ALLOY ALUMINUM, ARCHITECTURAL FINISH FOR MODERN HOMES: Clean parallel blades give walls, ceilings, or floors a hotel-quality, built-in look that blends into modern and contemporary interiors. Made from heavy-gauge alloy aluminum with precision-spaced black blades - no plastic parts. Rust-proof, warp-resistant, and built to last. The powder-coated surface wipes clean with a damp cloth and can be spray painted for custom color matching. Hidden side screws keep the face clean with no visible fasteners. Available in white and black, including a black finish popular for dark ceilings and industrial-style interiors.
- MULTI-DIRECTIONAL AIRFLOW CONTROL - QUIETER OPERATION THROUGH WIDER BLADE SPACING: Precision adjustment bar directs airflow left, right, evenly to both sides, or fully closed to block unused rooms - without replacing the unit. The GREEN VENT Slim linear slot diffuser features wider slot openings than competing models, allowing air to pass at controlled velocity and with less turbulence. This is a deliberate engineering choice that results in measurably quieter operation at equivalent airflow rates - addressing the rattling and whistling common with narrower-slot designs. Ideal for bedrooms, nurseries, home offices, and open-plan living rooms where quiet, controlled airflow matters most.
- 5-MINUTE RETROFIT INSTALL - FULLY REMOVABLE, SCREWS AND TOOL INCLUDED: Designed as a direct drop-in replacement for standard duct openings - no modification required. For wall and ceiling installation, mounts with 4 screws through pre-drilled hidden side holes, with no visible fasteners on the face and no drywall edge damage. Only a screwdriver and the included blade adjustment tool are needed. For floor installation, simply drop into the existing opening - no screws or tools required. Fully removable and reusable. GREEN VENT customer support is available before or after purchase.
- CEILING, WALL & FLOOR INSTALLATION - SUPPLY AND RETURN AIR COMPATIBLE: Installs on ceilings, walls, and low-traffic floors for both supply and return air use. Ideal for bathrooms, kitchens, living rooms, bedrooms, home offices, and light commercial spaces. For floor use, install in low-traffic areas only, not high-footfall paths. For return air applications, this diffuser is not compatible with standard air vent filters - the main filter should stay at the air handler. The powder-coated aluminum finish is UV-stable and corrosion-resistant, suitable for covered patios, garages, and enclosed porches, but not for direct rain exposure.
- HOW THIS DIFFERS FROM STANDARD VENT COVERS, PLASTIC ALTERNATIVES, AND STANDARD LINEAR SLOT DIFFUSERS: Unlike traditional louvered steel grilles, this linear slot diffuser delivers smoother, wider airflow to help reduce hot and cold spots in larger rooms. Unlike plastic alternatives, the alloy aluminum construction resists warping, yellowing, and cracking. The adjustable blade system supports 1-way or 2-way airflow control. Like all linear slot diffusers, this model has a narrower face panel than traditional grilles for a cleaner look. Compared with the standard model, the Slim series has a shorter neck depth for shallow duct cavities.
- DESIGNED FOR RENOVATION, NEW CONSTRUCTION AND MODERN INTERIORS: The flush-mount linear blade profile is ideal for renovation projects replacing outdated louvered grilles with a clean architectural finish. Its slim neck profile fits spaces with limited duct cavity depth with no ductwork modification required. Designed for direct retrofit into standard duct openings. Often chosen for new construction and remodeling by interior designers and HVAC contractors. Well suited for open-plan living areas, master bedrooms, modern kitchens,home offices, complements modern, Scandinavian and minimalist interiors.
- IMPROVE ROOM COMFORT AND AIRFLOW DISTRIBUTION - REDUCE HOT AND COLD SPOTS: Unlike fixed grilles that push air in one direction, the multi-directional blade system distributes conditioned air evenly across larger rooms - reducing the temperature imbalances that make living rooms and open-plan spaces uncomfortable. Close the blades fully to redirect heating and cooling away from unused rooms, reducing energy waste. Works as both a decorative supply air register and decorative return air grille - compatible with most residential HVAC systems for heating, cooling and ventilation applications across ceilings, walls and floors.
- QUICK ANSWERS TO COMMON QUESTIONS ABOUT THIS VENT COVER: Filter? No - air filters belong at the air handler or furnace, not at individual vent covers, as vent filters restrict airflow and strain the HVAC system. Can it be painted? Yes - lightly sand, prime, and apply standard spray paint for a custom color match. Outdoor use? Yes, in sheltered locations like covered patios, garages, and enclosed porches - not for direct rain exposure. Metal? Yes - 100% aluminum alloy, no plastic parts. Shallow duct cavity? Yes - the Slim Design has a shorter neck for shallow duct cavities.
