ILA Internal cascade for DN 1200 manholes for connection of sewage systems of different heights, downpipe DN 160/160, gray color ILA1200160_0000

The internal ILA cascade is used to connect sewage elements of different heights. The following nominal diameters are available: DN/OD 160, DN/OD 200, DN/OD 250. Cascade provides optimal protection against corrosion and is suitable for installation in DN 1,200 or newly built wells in existing concrete wells. The opening enables trouble-free inspection and cleaning. Since the installation of the cascade does not require much space, you can still move freely in the sewer well. Unlike external cascading wells, only a small trench is required, which saves time and money. Indoor installation is safer and easier. The set includes: • internal cascade with pre-drilled holes for mounting on the chamber wall, the set includes 3 stainless steel screws / wall plugs • stainless steel clamp for fixing
