Automatic attachment for a Louvre vent, fits most louvres.  Its fully adjustable to open over a range of temperatures.

Some drilling is required to fit.

Please note that an auto louvre can NOT fit a louvre which is directly left of an a-frame when you look at it internally without extra packing. 

Q. Can these auto vents be used with a double opening window, should I buy 2 of them?

A. A double sized (1200mm + wide) single vent would require 2 of these Auto-vents. I would recommend the stronger BAYLISS XL auto-vent openers for a large vent like this for extra reliablity during windy conditions.

Work very well quietly automating the vents. Fitting is straightforward as long as the instructions are carefully followed. May need drilling to reposition and fit. One failed and was replaced without fuss. Thank you.
