Abstract: The invention relates to a base plate (2) in a cable distribution cabinet. The base plate (2) is divided into two. The rear half (2a) can be folded down and the other half (2b) can also be inserted from the direction of the lower base chamber (3). The base plate (2) is sealed from the cables (15) with the help of sealing blocks (5) of a closed-cell foam and not by means of rubber grommets. The sealing blocks (5) have a height of several centimeters and, with that, a high sealing length. Any shifting of the sealing blocks (5) is prevented by threading them on guide rods (14).
