This vent is very functional. Simply, if the air inside your cabinet is not circulating, you need to use an air vent grille for ideal ventilation of closed spaces and allow air to circulate. Vents are recess mounted and suitable for many spaces - they can be used on a worktop, plinth, or cabinets. Vents can be cut down in length. Our vents are easy to install. Also, they can be easily cleaned during use. The vent is corrosion-resistant and waterproof. Width - 480 mm Height - 80 mm Depth - 16 mm Material - Aluminium Air throughput - 164 square cm
