ABSTRACT:
A bracket for mounting an electrical box on a wall stud including a sheet metal plate having front and rear faces and a large central opening therein. A pair of screw opening formations is provided in the plate generally adjacent diagonally opposite corners of the central opening in the plate. Each formation includes a relatively narrow screw shank clearance slot which receives the shank of a respective box mounting screw. The plate is so configured that an electrical box may be moved to a first position in which the front of the box is closely adjacent the rear face of the plate, and then to a second position in which the shanks of the mounting screws are received in the screw shank clearance slots of respective screw opening formations and in which the front opening of the box is generally in register with the central opening in the plate. A locking device on the bracket prevents movement of the box from its second position back to its the first position for locking the box in its the second position and holding the box captive on the mounting bracket without the need to tighten the box mounting screws.
