The Rhino Trailer Hitch Lock is a reliable anti-theft device to protect your trailer from theft. The massive metal lock that locks the hitch ball prevents the trailer from being disconnected without a key. The device is made of solid steel, making the lock extremely difficult to break into with common tools. The Rhino Lock is powder coated for added protection. Installing the lock takes only a minute - just insert it into the hole and turn the key. Such a simple and reliable mechanism guarantees the safety of your trailer even when you are not near the vehicle. The lock is compact and does not interfere with driving. But at the same time, its solid body protects the hitch reliably.
