Rated 5 out of 5 by from Well thought out timesaver Well made product that is simple but effective in its design. Certainly a life saver as far as working from height is concerned also removes all the need for faffing about with fixing additional external grills. Looks good and does the job. Just brought hence the rating for performance and reliability but expect them to also be long term 5’s.

Rated 5 out of 5 by from Very useful and great quality This is a great piece of kit, easy to use, great instructions, a good little video online too. I had an extractor fanto install 4 stories up in a flat, this item saved me all the trouble of scaffolding and ladders etc. Just drill the 117mm hole and slide it in. Nice and easy.

Rated 4 out of 5 by from Remember the angle I rate this product. It got me out of a bind. Bathroom extractor fan venting through gable end wall from the loft. I core drilled from the loft inside. There is a single storey room on the gable end side of the house so fixing a vent from the outside wouldn’t work as getting a ladder to the loft height is not possible with the single storey room in the way where the ladder would need footing. This kit made fitting a vent from the inside possible. Tip 1 watch the helpful manrose YouTube video demonstrating the fitting. Tip 2 get the angle right on your core drilling. Not level. But not too much of a slope either. My first core drill was too steep and the rubber seal on the outside would not lie flush with the wall and looked awful. Bottom was flush. Top was out from the wall cos of the angle. There was white pipe showing. Had to do a bit of “adjusting” drilling but got there in the end. Tip 3 be careful core drilling if a DIY’er like me you may be a novice and maybe have an sds drill but not expensive specialist core drill with safety clutch. Watch you don’t break your wrist the kick back from the drill when your core drill bit bites occasionally. Happy with the finished result.

Suitable for portable air con

Hello Can I use this to permanently vent my portable air con units to the external wall ? I know this is only 4in and the air con hoses are 6 inch but I can buy a reducer for that
Asked by: Alexgabi22

Hi,What size hole would need to be drilled for this bit of kit to fit through.Would this fit into an already exsisting 100mm core hole i have or does the core hole size need to be 117mm for this kit to fit through.Can any one who has fitted one of these

Asked by: hyui

Is this suitable for bathroom extraction?

Please also confirm that this can be installed completely from inside - I’d be working in the loft and going out through the gable end, with no way of getting to the outside. Thanks
