An equipment cabinet for insertable electrical and electronic units includes stationary casing components and a door pivotally attached by means of hinges. The door and the end faces of the casing components disposed opposite thereto are each provided with peripheral edge strips which are bent inwardly at an acute angle of preferably 45.degree. and have parallel sealing faces that face one another at a slight distance. Between the sealing faces, spring-elastic seals are provided that may be composed of contact strips of an electrically well conducting material and rubber-elastic sealing strips arranged parallel thereto. Due to the sloped arrangement of the sealing faces, the spring forces F exerted by the seals are divided into two force components F.sub.1 and F.sub.2, with only the one force component F.sub.1 having to be overcome when the door is pushed shut.
