A electrical housing knockout device ( 4 ) having a bracket ( 5 ) with a horizontal side ( 7 ) perpendicularly secured to a vertical side ( 6 ) and a sleeve element ( 8 ) connected to the horizontal side ( 7 ). The sleeve element ( 8 ) includes a shaft ( 9 ) and a base ( 10 ) wherein a central opening ( 12 ) extends through the shaft ( 9 ) and base ( 10 ). The sleeve element ( 8 ) also includes a collar ( 11 )located between the shaft ( 9 ) and base ( 10 ) wherein the collar ( 11 ) has an aperture ( 14 ). The sleeve element ( 8 ) extends from the collar ( 11 ) at a predetermined angle. The collar ( 11 ) is adjacent to the horizontal side ( 7 ) and is positioned such that the collar aperture ( 14 ) is pivotal about a stopper ( 15 ) which extends from the horizontal side ( 7 ). A means for securing the bracket ( 5 ) to the interior of a junction box ( 1 ) or circuit breaker box ( 26 ) is also included.
