2 Pcs 5 " Round Louvered Air Vent, 316 Stainless Steel Marine Boat Vent Cover,louver, and air outlet, exhaust vent

Sealed lockers breed damp. A caravan boot, a boat side locker or an under-seat storage box with no airflow ends up smelling of mildew and rusting whatever is stored in it. These two round louvered vents mount on the surface of the panel and let the space breathe without opening a path for rain.

Louvres angled to shed water

The face is pressed into raised louvres rather than drilled with plain holes. Angled slots let air move in and out while turning driving rain and wind-blown spray down and away from the opening, which is the whole difference between a vent and a hole. Fitted as a pair, one high and one low, the two vents set up a convection path that keeps air moving without a fan.

316 stainless, chosen for salt

The body is 316 stainless steel, the grade specified for marine hardware because its molybdenum content resists the chloride pitting that salt spray and coastal air deliver every day. It arrives polished, which suits a vent that ends up on a visible bulkhead or door. On a boat, a camper or a canopy that lives near the beach, that grade decides whether the vent still looks right in five years or streaks rust down the panel.
