not much to write about, very easy to install and I guess sort of universal - the diameter is 10cm, exactly what I needed to get gas safety certificate.
Required me to support the flue - worked a treat X
Good quality, easy to fix & you don't need a a qualified engineer to fit. Any DIY can do in 10 mins
Product was as described and did the job perfectly.
Does what it says, ok quality, wanted one ideally with an L bracket but put a unistrut cantelever under and it’s rock solid.
