Alpha Slate Vent
Great roof vent
I looked at a lot of different products when looking for the right roof vent to use on a job and the reviews for this vent assured me that it was right for the job. It's a great item, strong and easy enough to install. I would definitely recommend this vent.

Just for those wondering, the size of this is 600mm X 300mm but will cut down to 500 mm X 250mm. Still too big for what I wanted so will have to return I'm afraid hence the average score. The duct insert is oval shaped and 410mm in diameter. Hope this helps someone before purchase.

A very strong vent that is well designed and has not allowed any rain to get through despite a very exposed coastal location with extreme gales int the Scottish Highlands. Yes you will need the pipe as per the other reviews, but that is good quality too. If you need more information go to the manufacturers (Manthorpe Building Products) and download PDF installation and product details. Recommended.

The vent is good and fits easily. It really should say that you have no choice but to buy the flexi pipe too since the spigot on the inside is a ridiculous shape and nothing else would fit! Why they're not sold together I don't really understand....
