This vent makes it simple to keep air circulating in and out of enclosed spaces. The sliding lever lets you open or close the vent to control airflow as needed. Four 2" ventilation holes in the back move air through the wall, and you can mount it so the louvers direct air upward or downward. It’s a quick way to add passive airflow without wiring or a fan.
Made with durable, rustproof aluminum front and back plates, this vent stands up to weather, road grime, and moisture. The insert is built from corrosion-resistant zinc-plated steel for extra strength. It’s a solid, lightweight vent that resists damage from frequent exposure to sun, rain, and vibration.
The vent measures 12-1/4" long x 10-1/2" wide and installs using 7/32" mounting holes spaced 2-7/8" apart on top and 3" apart on the sides (center to center). The 2"-diameter ventilation holes line up easily for drilling and cutting. Once installed, it gives a neat, low-profile finish against the wall.
This vent mounts on the outside only, so it works well in setups where you want to manage airflow without bulky hardware inside. Because it doesn’t include mounting hardware, you can choose fasteners that best match your wall material—wood, aluminum, steel, or fiberglass.
With down-facing louvers, the vent blocks most water when closed and still lets fresh air flow when open. It seals tightly enough to prevent noticeable wind noise while allowing minimal air passage under pressure, so it balances ventilation with weather protection.
