How is it fixed to the ceiling? on the corners where it meets the sides on that inner gutter/box section? got to do one of these for us soon. P
exactly right bayb'ham re: the steel "hooks" ,what I did to hold it in place is carry the 2x2 at the edge back a couple of inches and secure by a bolt through that at the back in to the gutter. Door now fitted - really pleased!! B
