Complete 3-Part Vent Kit - Brings together a white 500mm rigid duct, round indoor grille with insect screen and square external backdraught vent for a coordinated through-wall ventilation route.
For Everyday Household Rooms - Suitable for compatible 100mm ventilation projects in bathrooms, kitchens, toilets, cloakrooms, laundry rooms and utility rooms.
Helps Restrict Insect Entry - The indoor grille includes a nylon screen that helps prevent insects from entering the ventilation duct while allowing air to pass through.
Helps Reduce Incoming Air - The external grille features a one-way shutter that supports outward airflow and closes when airflow stops, helping reduce backdraughts from outside.
External Fixings Included - Supplied with 4 screws and 4 wall plugs for securing the external grille, keeping the required exterior fixings together with the vent components.
