✓UNIQUE KEY DESIGN: Our trailer lock has a special key design that prevents anyone from picking the lock. This innovative key system also features an interior locking mechanism that stops would-be thieves from making a copy of your key.
✓CUSTOM TRAILER-COUPLER LOCK: Our patented lock design will allow you to secure most standard S-hook style safety chains in lock. This custom-tailored lock will only mount on specific 2-inch couplers. Make sure to check the coupler sizes that are compatible with our lock hardware to ensure that the lock you select matches your trailer coupler.
