"STOP!! READ THIS. Nothing wrong with this item but... compatible with SUA pipe adapter????? yes, but Screwfix does not supply this. Until I bought this item I wasn't sure what to expect. As I am using this to connect 100mm flexible ducting for my bathroom extraction I realised after purchasing that the adapter is needed. Didn't take back to screwfix, as builder doing the work had requested this item as he likes them. Found the Compatible with SUA pipe adapter elsewhere, but including postage comes to about another £20. So all in all quite expensive compared to other items available on screwfix."
"Everything about this slate vent is good, it's design and the way it installs invisibly. Until you try to attach your extractor or vent pipe to it. In the product info it states "Compatible with SUA pipe adapter." Why don't screwfix either supply it with the adapter or offer it as an option as with similar vents. I bought this and wasted a load of time trying to find a supplier of the adapter without success from any number of building and roofing suppliers. Come on Screwfix check your products for usability!"
