A locking system securing an image scanning device to a container includes a first and second compressible material. A first securing plate is disposed between the first and second compressible materials, while a second securing plate is adjacent to the second compressible material on a surface opposite a surface of the second compressible material that is adjacent to the first securing plate. A ball is disposed within curved edges of the first and second securing plates, where the curved edges each curve away from the second compressible material. A shaft extends from the ball to the image scanning device. A fastener is secured through the first and second securing plates, and into the securing surface to lock the ball, and subsequently the shaft and image scanning device, in place. The locking system can be secured to a pitched surface to naturally position the image scanning device perpendicular to level ground.
