Abstract: The present invention provides the means to encage the rear cargo area of a hatch back automobile with a freestanding cage that attaches to the vehicle to at cargo tie down points manufactured into the vehicle to provide security for the cargo area even with the rear seat laid forward and the hatch open. The cage is comprised of a pair of horizontal floor frames (18), a forward frame (30) that runs parallel to the rear seat (12), a horizontal top frame (9) that is formed to the shape of the cargo compartment and is hinged in the center (16) parallel to the fender walls (20) so it may be folded in half to ease assembly and storage, and a pair or rear frames (22) that run parallel to the hatch (38) and span the length of the hatch opening when joined together by a locking mechanism (26). The rear frames (22) are hinged (24) at the opposite ends of the locking mechanism (26).
