Proven Industries Model 2516 Trailer Lock, Made in The USA

The Proven Industries Model 2516 Trailer Lock delivers one of the highest levels of coupler security available, offering serious protection for trailers, campers, and cargo haulers that use select 2-5/16” couplers. Built from hardened steel, this lock is engineered to withstand aggressive theft attempts—including cutting, drilling, prying, hammering, and even power tools—making it a trusted choice for securing valuable equipment.

Unlike generic mass-fit coupler locks, the Model 2516 is custom-tailored to fit very specific 2-5/16” coupler models. This precise fit minimizes movement, reduces weak points, and creates a solid barrier that thieves cannot easily bypass. Owners simply need to confirm coupler compatibility to ensure the perfect match.

Security is further enhanced by Proven Industries’ proprietary key system. The unique key design resists picking and prevents unauthorized key duplication, offering peace of mind whether your trailer is parked at home, on the job site, or stored long term.

Manufactured in the USA with strict quality control from concept to fabrication, the Model 2516 represents Proven Industries’ commitment to producing the strongest and most reliable trailer security solutions on the market.
