{"title":"4x12 Modern Vent Covers","description":"\u003cp\u003eA 4x12 vent cover from Green Vent is a linear slot diffuser, not a louvered floor register — it's the modern, minimal-slot alternative for a 4\"×12\" wall, ceiling, or floor supply duct opening. If you're picturing a traditional wood or cast-iron floor register with adjustable blades, this isn't that product; it's a flush, architectural cover with a clean slot face.\u003c\/p\u003e\n\u003cp\u003eYou'll see this size written as both 4x12 and 12x4 — same duct opening, just a different order. Below: what this diffuser actually is, how to confirm your size, and the specs before you buy.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is This 4x12 Vent Cover?\u003c\/h2\u003e\n\u003cp\u003eThis 4x12 vent cover is a linear slot diffuser — a narrow-slot aluminum cover built for a 4\"×12\" supply duct opening, not a decorative louvered register. The distinction matters: a traditional floor register has adjustable blades or a damper you tilt by hand, while a linear slot diffuser has a fixed slot pattern with an internal adjustable airflow bar, giving it a flatter, more architectural look on the wall, ceiling, or floor.\u003c\/p\u003e\n\u003cp\u003eGreen Vent's 4x12 diffuser fits a duct opening measuring 4 inches by 12 inches, whether you see it listed as 4x12 or 12x4 — retailers write the dimensions in either order for the same size.\u003c\/p\u003e\n\n\u003ch2\u003eDuct Size vs. Face Size\u003c\/h2\u003e\n\u003ctable border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasurement\u003c\/th\u003e\n\u003cth\u003eWhat It Means\u003c\/th\u003e\n\u003cth\u003eYour Action\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e4x12 (Duct Opening)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThe hole cut into your wall, ceiling, or floor\u003c\/td\u003e\n\u003ctd\u003eMeasure this to order correctly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFace Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThe visible cover, roughly ¾\" larger per side than the duct opening\u003c\/td\u003e\n\u003ctd\u003eDo NOT use this to size your order\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e4x12 vs. 12x4\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSame duct opening — order just varies by listing\u003c\/td\u003e\n\u003ctd\u003eTreat as interchangeable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cblockquote\u003e\u003cp\u003e\u003cstrong\u003eMeasure your duct opening — not the old cover's faceplate.\u003c\/strong\u003e The duct opening is the actual hole, not the visible face of your current register.\u003c\/p\u003e\u003c\/blockquote\u003e\n\n\u003ch2\u003eThe 4x12 Aluminum Linear Slot Diffuser\u003c\/h2\u003e\n\u003cp\u003eGreen Vent's 4x12 diffuser is built from powder-coated aluminum with a 2-slot face, available in White and Black.
