The Dodge Charger (2015+) Single Cell Lite includes the Front Divider and Center Divider. The bottom 2/3 of the rear divider and center divider is powder coated steel with a built-in HSEP for added prisoner foot room. We didn't want to give prisoners a birds-eye view of the "good guy" side of the vehicle when you don't have to. The upper 1/3 is polycarbonate and has been designed to allow for prisoner viewing/interaction but not diminish drivers view out the rear view mirror. In fact, the visibility for an officer is nothing short of amazing.
