A metal door louver is a vented insert field-installed into a cut opening in a door leaf to allow air to pass between rooms while blocking direct sight lines. The slats are set at an angle so air moves through the blade openings without a straight view into the space behind.

Louvers of this type are typically supplied as a two-piece assembly: a frame with formed blades on one face and a matching trim frame on the other, fastened together through the door so that both sides are finished. The sheet-metal construction suits hollow metal and solid-core wood doors alike, and the exposed surfaces are normally primed or finished for paint to match the door.

Door louvers are the usual means of providing transfer air for mechanical rooms, closets and utility spaces where a return path is needed but a through-wall grille is not practical.
