Replacing, and in particular extending, the body of an outdoor distributor cabinet includes removing the body of the old distributor cabinet, slipping a new hollow base over the old assembly frame and the old base. A new body, which has at least the same inner capacity as the old body, is placed on top of the old assembly frame, aligned therewith, and secured. Accordingly, the distributor cabinet remains in its original position, whereby no new authorization for installation or building permit is required.
