HEAVY-DUTY COUPLER-BOLT LOCK: It’s important to do everything you can to protect your belongings and your trailer or camper from being stolen. Our strong lockset fits on adjustable couplers to help keep your trailer bolts secure.
TOUGH LOCK: The locking parts on this device are constructed from hardened steel for increased security, and the exterior hasp cover is tough enough to prevent burglars from using power tools, hammers, and crowbars on your lock.
UNIQUE KEY DESIGN: Our coupler-bolt trailer lock has a special key design on the puck lock 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 COUPLER-BOLT LOCK: This custom-tailored lock will restrict access to the bolts of your adjustable coupler. This kit includes 1 puck-style lock, 2 bolts, and 1 hasp shield. You will need to use your existing nuts to install the lock.
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.
