  • The cover serves to prevent backflow when draining drainage systems, pipelines. In the event of rising water levels (rivers, trails, lakes and the sea), backflow is prevented. The lid closes due to the lid closing automatically. The mass rise of the water level allows the bearing plate (fold) to be pressed against the sealing rubber, thus completely sealing the pipeline. The frog cover is also useful in flood protection because it prevents water from watercourses coming through pipelines into buildings. The frog cover prevents the animals from settling in the pipeline.
