Our Prisoner Transport Seats for the SUV come with either our Polycarbonate Window or Wire Screen Window Cargo Barrier to provide a solid mounting platform for the Seat to attach to. The seat and cargo barrier are designed to fit snug against one another as well as, the contours of the Tahoe to help prevent any gaps and crevices where prisoners might otherwise hide contraband or evidence. Each seat is molded from a single sheet of high strength ABS for durability that resists the daily abuse of transporting prisoners.
