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 in order to hold a ball mount or hitch-mounted accessory in place.
This lock will also work on the Twin Rack Bike Rack to prevent someone from accessing the mounting fasteners.
1/2" pin diameter to fit a 1-1/4" receiver tube size
Key-operated and activate with a simple 1/4-turn
Watertight dust cap to keep out the elements and prevent corrosion
