{"product_id":"12-linear-plaster-in-vent","title":"12\" Linear Slot Plaster-In Vent for Traditional HVAC","description":"\u003cp\u003eAdd a modern touch to your space with our 12\" Linear Slot Plaster-In Vent for traditional, conventional forced-air HVAC. The slot runs a full 12 inches and plasters in flush with the ceiling or wall, leaving nothing to look at but a clean line of airflow. Choose a 3\/4\" or 1\" slot height, rounded or rectangular ends, and a straight or 90-degree body — with a direct connection to 4\", 5\", or 6\" round ducting. Check spec sheet for dimensions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEven Airflow, Edge to Edge\u003c\/strong\u003e\u003cbr\u003eA 12-inch slot fed from a single round duct wants to blast air out the nearest end and starve the rest. Ours doesn't. Internal guide vanes and airfoils formed into the body split and steer the incoming air so it arrives smooth, even, and quiet across the entire 12\" span — no hot spot over the takeoff, no dead ends.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInvisible Integration\u003c\/strong\u003e\u003cbr\u003eThe perforated rim is engineered to be plastered over, so the vent disappears into the surface for a trimless, built-in look. No grille, no frame, no visual break — just the slot.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEngineered Versatility\u003c\/strong\u003e\u003cbr\u003eMatch it to the room and the system: a 3\/4\" or 1\" slot (the 1\" moves more air for larger rooms or higher airflow), rounded or rectangular ends, straight or 90-degree geometry, and a direct connection sized for 4\", 5\", or 6\" round duct. The 90-degree body turns the airflow inside the wall or ceiling cavity where a straight run won't fit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003cbr\u003eThe plaster-in body connects directly to your round duct and sets into the surface to be finished over. Choose the lip depth to match your finish: 1\/16\" for joint compound or 1\/8\" for plaster.\u003c\/p\u003e","brand":"HIFI VENT","offers":[{"title":"90 Degree - 3\/4\" - Rounded \/ 4\" Round Direct Connect \/ 1\/16\" (for Joint Compound)","offer_id":55037117038891,"sku":"12x0P75-90-RND-4DC","price":150.0,"currency_code":"USD","in_stock":true},{"title":"90 Degree -
