The universal tri-ball trailer coupler lock is engineered to be the ultimate in trailer towing security. It is highly theft-resistant and tamper-resistant, featuring built-in safety measures to keep your trailer safe. It offers security, whether your trailer is hitched up to your vehicle or left parked and unattended. This unique coupler lock has a lasso lanyard that is 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 constructed from high-strength, glass-filled polymer. This blend of materials is exceptionally durable and the orange color increases visibility to further deter tampering. The tri-ball lock fits all three industry-standard coupler and ball sizes 1-7/8, 2 and 2-5/16 in.
