I've a Velux GGL-9 skylight which I'm interested in temporarily removing, from inside the house, in order to get better access to the roof.
Attached to the window hinges are two curved metal plates that slot into a metal frame on the fixed surround. AFAICS it's simply a slot-headed screw bolt near the end of each plate that prevents the window from being removed. Screwing them both in slightly so as to be flush with the plate looks as if it will allow the window to be lifted out.
Can anyone please confirm that this is so and easily done and, more importantly, that slotting the window back in again afterwards shouldn't be problematic.
