Aria Vent presents its Flushmount Pro air register for use anywhere—floors, walls, ceilings—with any surface material. The air vent has optimal air flow performance, and can be regulated by sliding tray and accessing flanges that open and close. Both child and pet proof, the vent catches items and stops them from falling into the ducts as well as lays flat with no crevices so nothing can get caught. Air vents come in one color and size: 4 by 10 in. and matte black.
