100mm 4 Inch Wall Vent Kit with 500mm Duct & Black Backdraught Grille for Bathrooms, Kitchens, Toilets, Cloakrooms & Utility Rooms

Complete Wall Ventilation Set - Avoid sourcing the main components separately. Includes a white 500mm rigid duct, adjustable indoor grille, black external louvred grille, 4 screws and 4 wall plugs.

For Everyday Household Rooms - Creates a direct through-wall airflow route for compatible 100mm ventilation systems in bathrooms, kitchens, toilets, cloakrooms, laundry rooms and utility rooms.

Adjust Airflow from the Room - Turn the built-in control to increase or reduce the open area of the indoor grille, helping you manage airflow to suit the room and connected ventilation system.

Helps Restrict Insects and Backdraughts - The indoor screen helps restrict insects entering through the duct, while the one-way external shutter helps reduce incoming air when outward airflow stops.

Clean Finish Inside and Outside - The white circular grille provides a neat room-facing appearance, while the black square grille completes the outside wall with a discreet contrasting finish.
