A lever lockout assembly includes a pair of lever supports and a pair of slide supports mounted on a housing. A lever member is rotatably supported by the lever supports. The lever member has a pair of arms separated by a notch. A lockout slide is slidably supported by the slide supports. The lockout slide has a ridge portion and a recess portion. The lockout slide is slidable to a lockout position wherein the ridge portion is received by the notch and the ridge is engagable with the arms to prevent rotation of the lever member. The lockout slide is also slidable to an unlocked position wherein the recess portion is aligned with the notch and the arms are rotatable through the recess portion. A handle projects from an end of the lockout slide. The lockout slide is a rigid bar with a polygonal cross-sectional shape. An edge of the bar forming the ridge portion. The lockout slide includes a pair of detent recess formed in a surface thereof. A detent roller engages the lockout slide, and is releasably received by the detent recess to releasably hold the lockout slide in a selected positions.
