Roof passage and method for its production

摘要

The roof passage has an adapter ring (1) for attachment of standardized top parts. The adapter ring has a duct flange (3), which is inserted partially into an insertion opening. The flange is provided with an outer ring (5), which is adapted to a surface contour of a roofing tile. The flange has a lower section (6), which is inserted into the insertion opening. Fixing units (7-9) are provided for positioning the adapter ring to the roofing tile. An independent claim is also included for a method for manufacturing a roof passage.
