The CURT 23082 Universal Tri-Ball Trailer Coupler Lock delivers versatile, heavy-duty security for virtually any standard coupler-style trailer. Engineered to be highly theft-resistant and tamper-resistant, this coupler lock protects your trailer whether it is hitched to your vehicle for towing or left parked and unattended.
The unique tri-ball insert is sized to fit all three industry-standard coupler and ball sizes, eliminating the need for multiple locks across different trailers. A key-operated lasso lanyard locks the coupler latch securely in place during both towing and storage, keeping all components tethered together so nothing gets lost. An adjustable 1/4 in. locking pin accommodates coupler latch spans from 1 in. to 3 in. for a broad range of compatibility.
Constructed from high-strength, glass-filled orange polymer, the tri-ball body is exceptionally durable and highly visible — a deliberate design choice to further deter tampering. If a theft attempt is made, the lock is engineered with built-in safety break points that keep the ball lodged in the coupler, continuing to block unauthorized hookup. Two keys are included for convenient access. Covered by U.S. Patent 11,577,564.
