## Questions & Answers

**Q: Is this rooflight the vented version**
A: This version opens by pushing on the two arms. Also it can be tilted in all 4 directions.  However air does not flow through when fully closed.

**Q: what is the over hang measurement to cover  the orignal screw holes ,needs to be 50x50**
A: Suggest you check the website specifications carefully as I think it only overhangs 25mm all round.

**Q: How do i fot this to a shed roof.  Ie Under the felt or on top**
A: The fitting is for a caravan, I fitted it on a Hobby 495 on the roof. It needs to be sealed to stop ingrest of rain.

**Q: What is the depth of the roof needed. As I have a pop. Thanks**
A: Go to the advert and then I believe 'Specifications'. It lists two sizes dependent on the thickness of the roof.
