Stud and Screw Terminals 1 Circuit	Stud and Screw Terminals 2 Circuits

Protect connections against corrosion. These bars are tin-plated copper and have stainless steel terminals. Also known as bus bars, they serve as connection points between wires with ring or spade terminals. The underside is sealed, so the bars can be safely mounted to conductive surfaces.

Distribution Bar Covers—Distribution bar covers protect the top of the bar and prevent accidental contact with live circuits.

Modular Distribution Bars

Build your own distribution system for neutral and grounding applications by adding terminal blocks to these bars. Slide blocks onto the bar, also known as a bus bar, and then attach mounting brackets to the bar. All wires make contact with the bar, distributing the current among the terminal blocks.

Terminal Blocks

Terminal blocks have screw-clamp terminals that secure the wire as well as the block to the bar. Blocks are UL recognized for grounding applications.
