ABSTRACT:
Housing for electrotechnical equipment comprising two side walls, a top wall and a bottom wall which form a box-like framework with two openings which are sealable by means of a back wall, door, or inspection window, whereby in at least corner areas of the top and bottom walls support legs are pivotally mounted which are adjustable from a retracted position in which they are flush with the housing walls to an extended position in which they are perpendicular to the top wall and the bottom wall. Stacking of a plurality of housings such that they are prevented from shifting is attained in a simple manner in that at least the legs of the bottom wall are designed as stacking legs, and at least the legs on the top wall when they are in the retracted position form stacking seats for retaining the terminal ends of stacking legs of the adjacent housing which have been adjusted to the extended position.
