Abstract: A vertical back plate member is provided for mounting to a bumper. A pair of parallel side members extend from the back plate. A partition member joins the side members and forms a socket area with the back plate and side members to receive and position a bumper rack member in a vertical position. A strut member joins the side members near front edges of the side members and is positioned below a bottom edge of the partition member such a distance so as to permit a bumper rack member to be inserted between the bottom edge of the partition member and the strut member. Each side member has aligned first holes between the bottom edge of the partition member and the strut member to receive a pin which passes through a rack member to prevent horizontal movement of the rack member and to serve as a pivot point for movement of the rack member from a horizontal position to a vertical position.
