ROOF EXIT WINDOW JUNCTION
The plates should be assembled up to the roof exit window like always.
Measure the roof exit window, with the use of a fine-toothed saw open up a hole with these exact measurements.
Place the upper hinge over the shingle plate for lower junction and shape the place with your hands for a snug fit.
Then place the shaped plate at a position that will fit the diagonal and upper junctions and semi-overlap with the end points of the lower elements and the front hinges of the lower part of the window.
