Used for covering fallen trunks. The model has a double pipe and is used when the downspout breaks through the roof surface. The movable double pipe is pushed down into the drop stem, where it closes tightly with a rubber ring.

The drop stem covering ensures a watertight covering in the roof surface itself and ensures an airtight extension of the drop stem up to the opening above the roof surface.
