It is applicable to the connection of DN150 laterals to DN300 – DN600 gravity sewers or surface water pipe.
The FA 150U saddle enables a secure and leaktight lateral connection to be made to a larger sewer or surface water pipe without the need to excavate and disturb the bedding.
A cored hole is required having a diameter of 172 mm (+1/-0) and can have a deflection on the lateral of up to 7 degrees.
