Cannot be installed with cabin back mold, deck box, or FRP cargo cover. A portion of the cargo mat is required to be cut to fit together with a cargo mat. In that case, the Super Carry Cargo Mat will not be easily attached or detached. For Super Carriers, you can attach the top bar to a more flat surface by turning the hand tightening knob into the included screw. In that case, the bar cannot be opened and closed.
