HEAVY-DUTY TRAILER LOCK: It’s important to do everything you can to protect your belongings and your trailer or camper from being stolen. Our strong coupler lock fits select Fulton-style couplers that have a raised bump head and a trigger latch.
TOUGH LOCK: The locking parts on this device are constructed from hardened steel for increased security, and the exterior cover is tough enough to prevent burglars from using power tools, hammers, or crowbars on your lock.
UNIQUE KEY DESIGN: Our trailer lock has a special key design that prevents lock picking. This innovative key system also features an interior locking mechanism that deters 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 mount only on very specific Fulton-style couplers. Check the coupler sizes that are compatible with our lock hardware to ensure that the lock you select matches your trailer coupler.
PROVEN INDUSTRIES: We are dedicated to providing our customers with the most-effective trailer locks on the market. We carefully research and manufacture our locking systems from conception to fabrication in the USA.
