WARNING: Cancer and Reproductive Harm -

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. While a CURT hitch pin does offer sufficient strength for keeping your ball mount firmly attached, a CURT hitch lock goes one step further.

CURT hitch locks allow you to lock your ball mount into your trailer hitch, deterring theft and preventing anyone from detaching your trailer at the ball mount and towing away your property without your permission. This CURT hitch lock features a deadbolt design and comes with a 5/8" pin diameter to fit a 2", 2-1/2" or 3" receiver tube size. CURT deadbolt hitch locks have a solid, square-shaped lock mechanism and a bent handle for easier gripping. They are key-operated and activate with a simple 1/4-turn. They also come with a watertight dust cap to keep out the elements and prevent corrosion.

For the ultimate in towing security, a hitch lock and coupler lock used together will provide security at both the vehicle-side and trailer-side of your towing setup. For your boat, ATV or camper, keep your toys more secure with CURT hitch locks.

    Don't Buy this if your live in the north

    I made the mistake of leaving in my receiver for 6 months. When time came to remove it, its frozen solid. Ive used three types of lubricant to try and get the lock unfrozen. Its not moving.
    The lock will need to be drilled out or I will take a grinder to the pin.
    It works, but you should remove it after every use.

    Safety first!

    Everyone is talking about safety. But the most important information on the product package and the website is missing. Maximum weight that can be towed with the hitch! This is because I had a weird experience with another brand, providing class I-IV! As usual, everything is made in China! Missing German or Swiss quality!

    Does its job

    Had 1 of these for each of my trucks, they last years if removed immediately after use and wiped down. If you leave it in or don't clean road debris off after a week it'll be rusting. Switching to stainless, will see how those last.
