Telescopic cover for manholes DN400mm

This round, polypropylene telescopic cover from KARMAT is designed for riser pipes with a diameter of 400mm and provides a tight seal for the manhole. The telescopic design allows the cover to be adjusted to uneven terrain and compensates for surface movements, which is particularly important in areas prone to temperature changes. The cover, class A15, is characterized by increased durability – it safely withstands a load of up to 3 tons (30 kN), as confirmed by laboratory tests.

Application and installation

The cover is used in sanitary sewage systems, preventing unpleasant odors from escaping from inside the manhole. Installation is simple – the cover with a gasket is slipped directly onto the spigot of the riser pipe. The telescopic design facilitates precise adjustment to the surroundings, and the adjustable height allows for perfect leveling with the surface.
