Don't Just Lock Your Trailer. Make It "Unstealable."
As a towing and vehicle security expert, I see the tragic results of inadequate security all the time. A cheap, flimsy lock is an open invitation to thieves. Your trailer is a massive investment, often carrying thousands of dollars' worth of equipment, tools, or recreational vehicles. Protecting it requires a serious security device, not a suggestion. The Trimax UMAX100 Universal Coupler Lock is exactly that—a serious, robust piece of hardware that screams "go find an easier target."
Why a Clamshell Design is the Only Choice
A standard pin lock can be cut or defeated in seconds. The UMAX100 uses a superior **clamshell design** that completely encases the entire coupler. This brilliant design physically prevents a thief from being able to access the coupler or hitch a ball to it. It's constructed from solid **hardened steel**, making it incredibly resistant to cutting, drilling, and prying. Its universal fit means it's the one and only lock you need for your utility, boat, or RV trailer. For any serious trailer owner, this isn't just an accessory; it's essential insurance.
How to Use
- Select the appropriate ball size insert if needed for a snug fit.
- Place the main "clamshell" body over your trailer's coupler.
- Insert the hardened 9/16" steel shackle through the assembly.
- Lock with the key. The coupler is now fully protected and cannot be hitched.
