Other technical characteristics
This model is particularly indicated in areas where it's necessary to keep a certain uniformity and continuity with adjacent paving, in case materials like self-blocking porphyry, tiles and others are used, for example, in inner city squares and pedestrian areas.
Every lid is provided with two bottom-closed holes fit for lifting lever (eventually they can be supplied on demand), which facilitates the opening of the manhole top. The lids, thanks to their depth of joint, ensure a good stability during the ride of vehicles.
