Mounting foot assembly for lightbar

摘要

The generally rectangular support platform of a mounting foot primary component includes laterally extending tabs configured for reception in respective of longitudinally extending slots defined by an elongated strength member of the light bar. Diagonally opposite corners of the support platform are rounded off so that the primary component is installable by insertion toward the elongated member at an angular orientation and rotation to engage the tabs in the slots. The support platform defines a recessed channel for carrying a metal retaining bar. Fasteners passing through threaded openings in the retaining bar force the retaining bar and primary component away from the elongated member, placing the support platform tabs and lateral ends of the retaining bar in frictional engagement with the lips of the elongated member. A blocking bar is fixed against an end face of the primary component to block counter rotation of the mounting foot relative to the elongated member.
