An electrical box is described. According to one aspect of the invention, the back, top and bottom walls of the box are formed in one piece and have inwardly directed side flanges to which separate side plates are attached by screws. According to another aspect of the invention, the top and bottom walls of the box are fitted with U-shaped spacer elements which protrude from the box and form abutments against which a receptacle secured to the box is held. By adjusting the positions of the spacer elements, the final position of the receptacle can be varied, e.g. to compensate for inaccuracies in positioning of the box.
