Upgrade those basic, boring HVAC vents with this sleek, modern mud-in air vent cover. It's designed to be installed flush with drywall (you 'mud' or plaster around it), giving a super clean, built-in look. The face measures 18x8 inches, with a neck size of 17 3/4\ x 7 7/8\ to fit standard duct openings. It's made from solid extruded aluminum with a durable white electrostatic paint finish. Inside, it has directional dampers you can adjust to control airflow direction (90-degree spread or to one side). It can be used as a supply vent (blows air out) or a return vent (sucks air in) on ceilings or walls – just make sure to open the dampers fully or remove them if using as a return. It meets commercial HVAC standards (ASHRAE 70, ANSI S12.51) and moves about 285 CFM. Installation is a bit more involved than a snap-in register; you'll need to cut your drywall opening precisely and secure it during the finishing process. But the result is a high-end, architectural look that makes a big difference in any room. Perfect for modern homes, offices, or renovation projects where details matter.
