The CURT universal tri-ball trailer coupler lock is engineered to be the ultimate in trailer towing security. It's highly theft- and tamper-resistant, and it features built-in safety measures to keep your trailer safe. Whether your trailer is hitched up to your vehicle or left parked and unattended, you have that ultimate security. The one-of-a-kind coupler lock has a lasso lanyard that's key-operated. It allows the trailer lock to be used while towing a trailer, keeping the latch locked in place. It can also be used in tandem with the triple ball mount to fully secure the coupler when the trailer is parked.
The tri-ball is made from high-strength, glass-filled polymer. This blend of materials has exceptional durability, and the orange color increases visibility to deter tampering even further. The tri-ball lock fits all three industry-standard coupler and ball sizes: 1-7/8 inches, 2 inches and 2-5/16 inches. For more information, call 877-287-8634 or click here.
