Eccentric top cones for descending manholes are manufactured using polypropylene (PP) material. These cones are designed with reinforcement ribs and offer adjustability. The riser pipe can be reduced by up to 250 mm.
The various components are securely assembled using sealing rings to ensure proper sealing. The installation depth of the eccentric top cones should not exceed 6 meters, and the maximum permissible water table level is 5 meters.
