Manrose Round to Rectangular Flat Channel Connector 90° Elbow White 240mm is rated 4.0 out of 5 by 2.
Rated 5 out of 5 by from Works but beware You WILL need part (12697) round pipe connector added to go with this part as the round end is same diameter as 100mm round pipe. This differs from the 115mm rectangular to round version which does not require any other pieces. That said this 225 x 25mm system and ducting helped me to duct extractor over a steel beam in a 30mm gap. Another tip- outside dimension of ducting is approx 29 or 30mm- watch that one too.

Rated 3 out of 5 by from hear nor there the low profile of these system is so helpful and with the inner walls its sturdy but these adapters to 100mm round duct are 100mm so you need a joiner to connect anything just another part to buy and leek and wish i knew before trying to fit it all together
