The device is for the installation of electrical and pneumatic equipment in telephone exchanges and comprises an installation plate (1), relative to which rails (3) are fixable, with which the equipment is to be installed. The installation plate at opposite edges (7,8) is provided with components (9,10,15) for the adjustable fixation of the respective ends of the rails relatively to the installation plate in selectable positions. At least one component (17) rigidly lockable in a predetermined position relatively to an equipment rail defines a specific distance between this rail and an equipment rail to be fitted adjacent to it. The distance component is firmly locked between the equipment rails and the installation plate by pressing the equipment rail against the installation plate. |
