Why this ducting earns its place
When a kitchen extraction system vents to the roof, the duct terminal is exposed to everything the weather can throw at it. Rain runs down the outside of the building, wind drives moisture sideways into any opening, and gutters shed leaves and grit directly onto vertical duct exits. A rain cover is your first line of defence — it slopes water away, blocks debris, and keeps air flowing freely out of your kitchen.
This 350 mm cover is sized for standard domestic and smaller commercial kitchen extracts. It weighs just 1 kg, so it's straightforward to install on new systems or retrofit to existing ductwork. Combisteel designs for real working conditions: the cover handles thermal shock from hot extract air hitting cold rain without cracking, and it stays secure in wind without vibrating or leaking.
Whether you're specifying a new kitchen fit-out or retrofitting protection to an existing system that's been taking weather damage, a correctly sized rain cover prevents blockages that kill extract performance and damage ducting integrity over time.
