Abstract: This invention relates to an Electrical Junction Box with an external Built-in Fitting and clamp for securing armored metal cable to the Electrical Junction Box. The Built-in Fitting is extruded from a side wall of the Electrical Junction Box and has at least one pry-out for receiving an armored metal cable. A clamp is attached to the Built-in Fitting with threaded fasteners. As the threaded fasteners are tightened, the armored metal cable is clamped in the opening of the side wall of the Built-in Fitting.

Abstract: The Adjustable Mud ring consists of a collarless frame, having a central opening for an Extending Member, perimeter fastener openings for connecting to a junction box, and bendable tabs for securing the frame to an Extending Member, which is boxed shaped with a central opening for electrical apparatus, fixed tabs with openings for threading adjustable fasteners into openings in the frame, and bendable tabs for securing the system to a wall. A Grounding Spring Clip, constructed from sheet-metal, folded to create a compressive spring, with an opening for a fastener, allows proper grounding. Add-on Rings are boxed shaped with a central opening, openings on flat, fixed perimeter tabs for threading bolts into to an Extending Member, and bendable tabs for securing the system to a wall. A bracket, with openings for fasteners for attaching the assembly to wall members, can be made a part of the frame.
