Now for some Roof Fans





One here I think



Lets make the frames, 38 mm will end up the correct level for the head lining.





Looking on Utube some people had a hole of 355 x 355 but after looking at the flange for this model 500KI40 it needed to be 400 x 400 so  I measured and measured until I was certain. 

























Some masking tape so I don't scratch the lid.
























A old bag to catch the steel bits.





























Dam ribs are a pain you have to make up 4 layers with the mastic tape then one band all over the top. 






That's the rear one done, I wish I had done the front one first. Much easier as the roof has a handy square with no ribs which just takes 400 x 400. 


And one the other end (Front) O and here comes the rain.


pre drill the holes  
























This time with lessons learned put the mastic tape on the lid then some black Sika flec 211.
























A long thin screw in opposite corners just to line up and boom spot on. 
























Put all the supplies stainless screws in and slowly torq down evenly to get Sika fec oozing out.


























Getting  the 2 screws in each side is a bit of a pain as you cant push don too much but you do need to push enough to get the holes to line up.
