Protective Products International's (PPI's) Covert Ballistic Door Panels offer a level of protection unmatched by any other OEM police vehicle. With this extra protection, officers can swing their vehicles' front doors into action as a tactical shield from incoming projectiles. Specifically developed for the Ford Crown Victoria Police Interceptor, the ballistic door panels are covert (not visible from the outside), lightweight and don't interfere with interior space or door/window mechanisms. The panels are certified to stop all NIJ level 3A rifle rounds. PPI's panels also have been crash certified, passing Federal Motor Vehicle Safety Standards and are available as fleet or aftermarket purchase.
