ABSTRACT:
A lock-out device for electrical circuits which includes an elongated, open sided C-shaped housing having parallel side walls each joined at an edge to a back panel. Each side wall defines a plurality of spaced, open slots. The slots in the side walls are paired in transverse alignment, and dimensioned to receive elongated locking pins. Each locking pin carries spaced annular grooves dimensioned to permit each pin to be engaged by the two side walls when the pin is placed in two aligned slots in a slot pair. A cover plate hinged to the side walls at one end of the housing pivots between an open position and a housing closed position in which it prevents removal of the locking pins from slot pairs in which they are received.
