Telescopic polypropylene cover class A15 (1.5t) DN 315mm, tight with a socket, for smooth pipe, for sanitary sewage system PS315

The use of KARMAT airtight covers prevents the release of unpleasant odors from the sewage system, which is especially important if the well is located near the building. The assembly is carried out by sliding the cover with the gasket in the socket onto the manhole rising pipe. An additional feature of sealed covers is telescopic movement.
