Upgrade your ventilation with this sturdy, good-looking vent cover from Vent Systems. It's made from galvanized steel with a brown epoxy paint finish that resists corrosion. The rectangular grille measures 4\ x 5.5\ for the opening, with outer dimensions of 5\ x 6.61\ and a 0.79\ flange depth. It includes a nylon insect mesh attached to keep bugs and debris out while allowing air to flow freely. The design is disassemblable – you install the frame into the vent opening (using mortar or adhesive), and the grille cover snaps on with side latches. That makes it easy to remove for cleaning or maintenance. This vent is perfect for intake or exhaust use on walls or ceilings in bathrooms, kitchens, garages, sheds, offices, RVs, or campers. It works with dryer vents, exhaust hoods, or general HVAC ventilation. The louvered design helps direct airflow and adds a clean, finished look. If you're replacing an old, rusty vent or adding a new one, this brown steel grille is durable, functional, and easy to install. A solid choice for any home improvement project!
