Universal Tri-Ball Trail er Coupler Lock

The Universal Tri-Ball Trailer Coupler Lock by CURT Manufacturing is a critical security device designed to prevent theft and unauthorized trailer movement. Built for law enforcement, fleet operations, and tactical personnel who require dependable equipment protection, this coupler lock addresses a real vulnerability in vehicle security—the hitch connection point. Weighing just 1 pound and measuring a compact 6 x 3 x 9 inches, it integrates seamlessly into pre-mission gear checks and daily security protocols without adding bulk to your tactical loadout.

Engineered to secure tri-ball couplers across three standard sizes—1-7/8 inch, 2 inch, and 2-5/16 inch ball diameters—the Universal Tri-Ball Trailer Coupler Lock accommodates the vast majority of commercial and tactical trailers in service. The polymer construction provides corrosion resistance critical for field environments and extended outdoor operations, while the bright orange color ensures visibility during equipment inventories and rapid gear audits. The hardened pin mechanism resists prying and cutting attempts, delivering the level of physical security required when protecting sensitive cargo, mobile command posts, or high-value equipment platforms.

Law enforcement agencies, military support units, and private security operations benefit most from this coupler lock's straightforward installation and universal compatibility. Simply align the lock with the ball coupler, insert the pin, and secure—no tools or training required. This product is essential for personnel operating equipment trailers in high-risk environments where trailer theft or sabotage presents operational risk. Installation takes seconds during hitch-up procedures, and the lightweight design makes it suitable for both permanent fleet security and temporary deployments where equipment mobility cannot be compromised.
