Rated 2 out of 5 by from Does the job Found these vents to be a little bit flimsy especially if the surface to which they were fixing was not dead flat. Vent louvres still allow a little air through when closed which was ok for my purposes but may not suit others.

Rated 5 out of 5 by from Great buy I bought this Vent screen to replace another plastic one which my our handyman attached to the kitchen wall. Never ever buy plastic one-the inner movable part is very wobbly and does not protect my house from the wind horrible draft. MAP VENT ADJUSTABLE VENT does its job! I could screw it to the wall, it stays very firm, and when closed I feel just very little air movement. I'd advise you to buy mosquito net to place inside (plastic one is better), and also you could purchase some rubber Foam Tape to secure the gaps between the wall and the vent if your walls are not perfectly straight as mine.

Rated 5 out of 5 by from Great product Great product. Perfect fit for my vent replacement. Very reasonably priced, and looked on other sites, but this was the best option. I would recommend this product in future.

Atual Size

Is 9x9 the channel size as stated. If so what is the item size - Edge to edge? I do not believe the item is square as indicated in your answer regards the holes distance being 230
Asked by: Mariner2000
Thank you for your enquiry. The overall sixe (edge to edge) of this vent is 240mmx260mm. The ventilation (screw hole to hole) size is 230mmx248mm. Thank you and kind regards

Why are some louvred vents suitable for gas appliances and some are not

Asked by: Nephets
Good Afternoon Many thanks for your enquiry. Vents suitable for gas appliances will have no fly screen. Gas needs a certain amount of oxygen to burn correctly. Every cubic metre of natural gas needs about ten cubic metres of clean air for complete combustion. A lack of oxygen causes incomplete combustion, producing carbon monoxide, a highly poisonous gas. Please ensure that the correct vent is used for gas appliances. Best Regards
