Manrose 150mm Gravity Shutter Grille – White
Made to the same reliable standard as the smaller sizes, this 150 mm grille is ideal for larger ventilation systems, such as high‑performance kitchen extractors or whole‑house ventilation setups. It is constructed from tough, UV‑stabilised white plastic that will not fade, crack or warp even when fitted externally and exposed to the elements.
The louvre mechanism works entirely by airflow and gravity — no electricity or moving parts required. When your fan runs, the flaps open fully to let air escape freely; once the fan switches off, they fall closed to form a secure seal against wind, rain, insects and back‑draughts.
Installation is quick and simple: the spigot pushes firmly into standard 150 mm ducting, and the wide faceplate covers the hole neatly. Pre‑drilled fixing points allow you to screw it securely in place for a long‑lasting finish.
