Manrose Chrome effect Rectangular Adjustable vent, (H)152mm (W)229mm

Exactly what I needed. Sit flat against wall and easy to use so even my wife understands how to open and close vent ;)

Firstly, this is a nice product, but anybody like me, who buys it to fit in a very particular way where the dimensions matter, might like to know its real size!

The vent cover is made to cover a very standard air brick vent, of nominal size 9" x 6". Somebody sitting in an office has converted the nominal size exactly into metric, and declared on the website that the product measures 229 x 152 mm (which incidentally it does not say on the packet).

However, as the nominal size has a margin around it, with extra for the fixings on two sides, the real overall size of the product is 260 x 165mm. That won't matter to most people, but to some it might.

In my case, I was able to adapt the mounting I needed to fit it to, and am still happy with the product. - Gentle suggestion, people sitting in offices could try checking with a tape measure in the warehouse?
