The invention relates to a distribution cabinet which is generally placed outdoors and integrates the technical, e.g. electric or optical distribution systems for weak current systems, e.g. telephone systems, with associated current supply devices and cable terminal and connection devices for a specific spatial area, in addition to a method for replacing, especially extending, the body of a distributor cabinet which is difficult to replace and wherein the distributor cabinet remains in its original position, whereby no new authorization for installation or building permit is required. This occurs as a result of a method for replacing, especially extending the body of an outdoor distributor cabinet. According to said method, the body of the old distributor cabinet is removed, a new hollow base as seen from below upwards is slipped over the old assembly frame and old base and is placed on top of the sub-structure and aligned therewith, whereby a new body which has the same inner capacity as the old body is placed from the top down on top of the old assembly frame, is aligned therewith and is secured.
