Secure trailers to vehicles by locking the hitch pin into the receiver—you can't disconnect the trailer without the key. Use them to prevent someone from stealing your trailer or moving it. Built to stand up to any weather, they're great for outdoor trailers. The lock body rotates around your hitch pin, so you can easily reach the key into the cylinder to unlock. A plastic cover protects the key cylinder from water and debris, so it won’t freeze, corrode, or jam.

Style A lock from the side of your vehicle—access to the key cylinder is perpendicular to the hitch. These locks do not include a hole for a cotter pin. Made of steel, they’re stronger than stainless steel locks. Chrome plating adds corrosion resistance. The included cover is a separate piece.

Locks for 2" square hitch receivers fit class III and IV hitches. Locks for 2 1/2" square hitch receivers fit class III-V hitches.

Choose keyed differently locks if you need locks that each open with a different key.
