In a dual-sided mounting bracket for electrical junction boxes, wherein the mounting bracket comprises first and second stud coupling members and first and second junction box receiving members adjacent the respective stud coupling members, and an offset portion interposed between the first and second junction box receiving sections, and wherein each junction box receiving section has two expansive sides and two lengthwise extending edges and is adapted for mounting an electrical junction box or electrical junction boxes to a given one of the expansive sides of such junction box receiving section, each junction box receiving section has two flanges, each extending along a given one of the lengthwise extending edges of such junction box receiving section and projecting from the other one of the expansive sides of such junction box receiving section, so as to project away from an electrical junction box or electrical junction boxes mounted to the given one of the expansive sides of such junction box receiving section. Each junction box receiving section has a single tab, which can be bent back so as to support said junction box receiving station against an adjacent wall panel, and which can be bent back along either of two bending lines, so as to accommodate either of two spacings from the adjacent wall panel.
