⚠️ CHECK SIZE BEFORE PURCHASE: This 10x4 linear slot diffuser fits a 10" × 4" duct opening (the hole in your wall, ceiling, or floor — not your old cover face). See the full 10x4 sizing guide → * Fits a 10" × 4" duct opening — measure the hole, not your old cover face. * 2-pack format — ideal for matching paired vents or updating two rooms with one consistent finish. * Drop-in surface-mount replacement — no drywall, flooring, or duct modification required. * Modern minimalist slot design for contemporary interiors and cleaner visual lines. * Solid alloy aluminum — rust-resistant, durable, and zero plastic parts. * Wall, ceiling, or low-traffic floor compatible — one diffuser, multiple install scenarios. * Multi-directional adjustable airflow — direct air left, right, both ways, or fully closed. * TÜV Rheinland tested — lead-free coating, phthalate-free materials, Prop 65 compliant, and corrosion-resistant finish. Designed for modern interiors, engineered for comfort Replace your dated 10" × 4" louvered grille with a modern aluminum linear slot diffuser designed for clean architectural lines. This white surface-mount diffuser installs on walls, ceilings, and low-traffic floors, giving existing duct openings a cleaner, more intentional finish. White finish pairs naturally with white trim, light ceilings, painted walls, Scandinavian interiors, and light wood floors. This 2-pack is designed for matching vents in the same room, paired openings, or multi-room replacement projects. Designed to upgrade, not to remodel A full remodel should not be required just to make a vent look intentional. This surface-mount diffuser upgrades an existing duct opening without cutting into the wall, ceiling, or floor. Inside: heavy-gauge aluminum, a multi-directional adjustable blade system, and a powder-coated finish made for everyday residential use. Outside: a clean slot profile that looks more refined than a bulky stamped grille. Sizing Guide — Will a 10x4 fit your space? IMPORTANT: Measure the hole in your wall, ceiling, or floor — do not measure your old vent cover. This 10x4 aluminum vent cover is designed to fit a standard 10" × 4" duct opening (also listed as a 4x10 wall register or 4 x 10 vent cover). * Duct opening size: 10" × 4" (this is what you measure) * Neck size: 9-3/4" × 3-3/4" * Overall face size: 11-3/4" × 5-3/4" * 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.
