GREEN VENT Modern AC Vent Cover 10x4, Premium Linear Slot Diffuser — Open-Box, 23% Off

FITS 10X4 DUCT OPENING – MEASURE THE HOLE, NOT YOUR OLD COVER: This aluminum linear slot diffuser fits a 10" x 4" duct opening. The neck measures 9-3/4" x 3-3/4" for easy insertion, while the face measures 11-3/4" x 5-3/4". The modern slot face is narrower than many old louvered steel grilles, so minor paint touch-up may be needed. See the sizing photo or contact GREEN VENT before ordering. PREMIUM LINEAR SLOT DESIGN – ALLOY ALUMINUM, ARCHITECTURAL FINISH FOR MODERN HOMES: Clean parallel blades create a hotel-quality built-in look for modern interiors. Made from heavy-gauge aluminum alloy with no plastic parts, this wall register resists rust, warping, yellowing, and cracking. The powder-coated finish wipes clean and accepts spray paint. Hidden side screws provide a clean flush finish. Available in white and black. MULTI-DIRECTIONAL AIRFLOW CONTROL – QUIET AC VENT COVER WITH WIDER BLADE SPACING: The adjustment bar directs airflow left, right, evenly to both sides, or fully closed. Wider slot openings allow air to move at a controlled velocity with less turbulence, helping reduce the rattling and whistling common with narrow-slot AC register vent covers. Ideal for bedrooms, nurseries, home offices, and living rooms where quiet airflow matters. TESTED SAFE FOR YOUR HOME: Every GREEN VENT decorative HVAC register and air vent cover is thoughtfully designed and crafted in Vietnam by skilled craftsmen. Each unit is made with careful attention to material quality, finish, durability, and everyday usability. Built to meet the expectations of U.S. homeowners and contractors, it provides reliable residential performance while adding a clean, modern architectural look. 5-MINUTE RETROFIT INSTALL – FULLY REMOVABLE, SCREWS AND TOOL INCLUDED: Designed as a direct drop-in replacement for standard duct openings with no modification required. For wall and ceiling installation, secure it through four hidden side holes using the included screws. For floor installation, simply drop the floor register cover into the opening. The blade adjustment tool is included, and the diffuser is fully removable and reusable. CEILING, WALL & FLOOR INSTALLATION – SUPPLY AND RETURN AIR COMPATIBLE: Works as a ceiling vent cover, wall register vent cover, or floor vent cover in low-traffic areas. Suitable for both supply and return air in homes and light commercial spaces. When used as a return air grille, it is not compatible with standard vent filters. The UV-stable, corrosion-resistant finish suits covered patios, garages, and enclosed porches, but not direct rain. HOW THIS DIFFERS FROM STANDARD VENT COVERS AND PLASTIC ALTERNATIVES: Unlike traditional louvered steel grilles, this linear slot diffuser creates a smooth, wide airflow pattern that helps reduce hot and cold spots. Unlike plastic AC vent covers, aluminum will not warp, yellow, or crack. Adjustable blades support 1-way or 2-way airflow control. The face panel is intentionally narrower than traditional grilles for a cleaner decorative appearance. DESIGNED FOR RENOVATION, NEW CONSTRUCTION AND MODERN INTERIORS: The flush-mount linear blade profile replaces outdated louvered grilles with a clean architectural finish. It directly fits standard duct openings without modification, making it ideal for renovations and new construction. This modern ceiling vent cover and wall vent cover complements Scandinavian, minimalist, contemporary, industrial, and luxury interiors. IMPROVE ROOM COMFORT AND AIRFLOW DISTRIBUTION – REDUCE HOT AND COLD SPOTS: Unlike fixed AC registers that push air in one direction, the multi-directional blade system distributes conditioned air more evenly across larger rooms. Close the blades to redirect heating or cooling away from unused rooms and reduce energy waste. Works as both a decorative supply air register and return air vent cover with most residential HVAC systems. QUICK ANSWERS TO COMMON QUESTIONS ABOUT THIS AC VENT COVER: Filter?
