ROOF CROSSING DEVICE ADAPTABLE TO A LARGE SLOPE RANGE

摘要

The present invention relates to a roof penetration device especially for the exhaust air or ventilation, and more particularly a roof penetration device usable for a wide range of roof slopes. The device comprises a plate (S) comprising a plate (1) provided on its upper face (la) with a dome (2), and a tubular element surrounded by a skirt of shape complementary to that of the dome, so that said skirt is able to cover said dome for different angles of inclination of the tubular element, said tubular element passing through an opening of the dome. The dome (2) has breakable parts (210) defined by lines of weakness, said opening being made by removing one or more breakable parts at the desired angle of inclination, and / or said skirt has portions breakable lines defined by lines of weakness, one or more breakable parts can be removed at the desired angle of inclination.
