The anti-tilt locking device is a bracket that can be used with your Class III hitch to prevent wobble when using a hitch mounted carrier or other product. This anti-tilt bracket works by pinching the main hitch tube of the towing product firmly into the trailer hitch receiver attached to your vehicle.
