<p>The passage through a roof, esp. in the form of a ventilating pipe, comprises a base component in the form of a roof tile, with a cupola-shaped bulge in the centre, and a tubular top component, witha hood piece overlapping the bulge and able to swing into differently sloped positions. An arched piece is set on the hood component (6), in the form of an extended section, stretching along the pivot plane and overlapping the bulge (4). This incorporates a slot (a), penetrated by a clamping screw (10). This screw maybe screwed into the bulge. The inclined setting of the tubular top component can be obtained without the use of benders.</p> |
