A ladder that clips over the top of the Discovery 3 & 4s / LR3, LR4's rear door and bolts behind the license plate. The ladder conforms to the contours of the vehicle and is constructed out of black powder coated mild steel to ensure durability and strength. Easy installation: the top part of the ladder clips over the rear door and uses existing mounting points for fitment. No drilling required. The top and bottom treads are textured for added grip and the top clip is lined with rubber to avoid damage to the vehicle's paint work.
