Looks to me like a fairly normal hitch, with some kind of bar on the top that sticks out over the cap on the tongue. Im guessing serving the purpose that if someone was to cut the lock on the trailer, they still couldnt unhook it b/c the bar covers the release. Just an extra safety measure I guess. First one Ive ever seen though.13 PIV w/ 200 MercIG: WarriorRiverCustomRods
