"Ideal kit for my tumble drier, to create a permanent vent. Much better than the plastic hose that disintegrated, and a nice finish to the wall. The vent flaps open easily so not too much back pressure."
"This Kit is better than the usual flimsy plastic vent kits. It can be formed into a sharp bend if necessary. It holds its shape very well so making good round it is easy. I used a 150mmm core drill to make the hole in the wall and then made good round the tube. I trimmed the tube to length afterwards using a trimming knife, as there is no spring steel spiral that needs to be cut with snips or similar. The only downside is that like nearly all these kits is that the mounting holes for the louvre outside are very close to the edge of the hole that you create, so the making good needs to be very good in order to get a fix for the screws. Making the plate for the louvre just a bit bigger would make a big difference to the ease of fixing. The louvres however do work well and unlike many others seem un affected by wind, so you don't get that annoying rattling noise in your kitchen when the wind is in the wrong direction"
"The Exterior grille is excellent but note that the metal expanding trunking is approximately 133mm diameter measured EXTERNALLY! So this trunking will NOT fit in a standard 130mm diameter core drilled hole!!"
"I have just read a few reviews on this because I have just fitted one of these and coudldn't get it through the 127mm Core Drilled Hole. I thought it was me, but evidently not. Beware, if using a 127mm core drill it will not fit, you then have to start chiselling out bricks to get it to fit which defeats the object!"
"Quality of product seems good but the width of the hose was closer to 130mm so would not fit in the 125mm hole drilled for it. The metal hose is too stiff to squeeze into the hole as you would be able to do with a PVC hose. Had to get separate hose to attach to vent grille and cooker hood."
"Use a piece of 125mm plastic pipe through the wall. This will mate with the spigot on the outer cover. Use a 125mm coupling to join the plastic to the aluminium. The plastic will fit core drill holes."
"A very good product but failed on Overall Rating for the following reasons It is sold as a 125mm duct but actually measures 130mm The duct is to big to use a 127mm core and to small for a 150mm It is also to big for the 125mm flanges on extractor hoods And finally the only way I have found to fit this into a 127mm hole is to crease it to reduce the circumfrence then use a lead paddle to shape it into the hole."
"Having used a 127mm core drill and cut a clean hole through a particularly thick wall I was not a happy bunny when the tube did not go through the hole! Having read other reviews I now see others have encountered this problem. Also being oversize it did not fit snugly onto the cooker hood outlet either. Would not buy again."
