The New Single Cell Lite for the 2021+ Ford F-150 SSV/Police Responder includes the Front Divider, Center Divider, Rear Window Armor and Door Window Armor. Jotto Desk realized the extreme challenge facing agencies in regard to the rear seat area of pickups and has created a solution for prisoner containment in those vehicles. The bottom 2/3 of the front divider and center divider is powder coated steel with a built-in HSEP (High Security Extension Panel) 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 the driver’s view out the rear view mirror. In fact, the visibility for an officer is nothing short of amazing.
