Abstract: An adjustable depth electrical enclosure is taught. Briefly stated, a load center housing has inverted T shaped slots provided along its exterior. A bracket having an adjusting screw swagged thereto is extended through the T slot so that the bracket can ride back and forth in the vertical portion of the T slot. The adjusting screw is rotatably attached to a flange on the enclosure such that rotation of the screw causes the adjusting bracket to move with respect to the front/rear direction of the enclosure. Thereafter, when the brackets are attached to wall studs, mere adjustment of the adjusting screw allows the enclosure to be moved perpendicular to the wall thereby allowing the enclosure to be accurately flush mounted with the wall material utilized.
