VEHICLE ROOF BOX WITH CENTRAL, EXTERNAL ATTACHMENT SYSTEM

A roof box for carrying cargo affixed to the roof rack rails of a vehicle is described. The attachment mechanism operates without the need to access the interior of the roof box itself and without disrupting the continuity of the floor board in the roof box. The user may deploy the engagement system from a single control point, and the individual attachment mechanisms include safety mechanisms to guard against an unexpected failure of other system components.
