Two lock options to suit your style and needs

• Vibrant colored puck locks offer eye-catching deterrence and quick visual identification for your rig.
• A sturdier silver steel option emphasizes higher resistance to cutting, drilling, and blunt force.

Wide compatibility for many trailers

With an adjustable locking mechanism, this trailer hitch lock fits most 1-7/8 in, 2 in, and 2-5/16 in couplers as well as Bulldog couplers. Its ball joint aligns the lock with the coupler for a snug, secure fit, and the design aims to minimize wobble and gaps compared with other locks.

Rugged protection you can count on

Constructed from hardened steel, the lock is designed to withstand sledgehammer-like impacts and prying attempts. The fully enclosed housing guards internal components from exposure, while a tight internal fit increases anti-pry performance to help protect your trailer during stops and overnight storage.

Weather-ready and durable upgrades

A full-wrap corrosion-resistant coating shields the metal from rain and harsh weather, helping maintain durability over time. The lock remains compact and easy to carry, with a design that fits couplers snugly and reduces any wobble that could complicate installation. The fact that the product is patent-pending signals a unique approach you won’t find in every lock on the market.

Security core and value-added features

Each model benefits from a heavy-duty anti-drill core that helps deter unauthorized key copying. The package is designed to be gift-ready and the brand provides reliable support, including a lifetime limited warranty for buyers. This makes it a practical choice for weekend campers or long-term storage needs, whether you’re maintaining a small trailer or a heavier setup.
