Manrose 100mm Gravity Shutter Grille – White
This high‑quality grille from Manrose provides a neat and functional finish for ventilation ducts. Manufactured from durable UV‑resistant white plastic, it is suitable for both internal and external use, maintaining its appearance even in exposed conditions.
The key feature is the gravity‑operated louvres: they open freely under the airflow from your extractor fan, and fall closed once the fan stops. This creates a tight seal that stops cold air, wind, rain, dust and insects from entering the ductwork and your living space.
It is lightweight, easy to fit, and compatible with all standard 100mm (4 inch) diameter ducting and extractor fans. The square faceplate gives a clean, modern look and covers the hole neatly for a professional finish.
