Hitch Locks
Make your tow vehicle and trailer more secure by keeping them locked up tight with a CURT hitch lock. Like a hitch pin and clip, a hitch lock is designed to insert into the fastener hole in the side of a receiver tube and hold a ball mount or hitch-mounted accessory in place. While a CURT hitch pin does offer sufficient strength for keeping your ball mount firmly attached, a CURT hitch lock goes one step further.
