Hi Paul
wrong size
I believe a replacement has been organised by my colleague and you should receive the item shortly.
Just received the above from you. I note only one spring . Do you do a two spring version and is the one spring ok for horizontal and vertical fitting
Hello Graham
Can this be fitted inside a 5" flexible duct by pushing it in through the exit hole, which is horizontal?
