Реферат: The manhole has cable box plates, side plates and a cover plate. The U-shaped frame opening faces downwards. These frames (4, 5) have links at the top, sloping at least one the outside towards the cable box plate. It holds together different components (1-6) by its stepped profile. The base plate has a surrounding edge stepped piece (9). This edge piece projects over the middle surface of the base plate which can be providced with a well- like recess (11). The components can be installed in the angle formed and sealing material inserted around them. Mounting is mostly at right angles for ease of working.
