Floor or roof outflow

摘要

A number of burls (10) in the area of the rolling path are distributed over the periphery of the insert connection (2). The burls in their horizontal cross section have a trapezoidal profile and also in their vertical section. The odour closure insert part (1) comprises a connection receiving the roller ring, which is extended upwards as an overflow collar (3) over the bell closure (4) engages. The bell is permanently connected to the overflow collar and at the top has a handle (5).
