Developed in close collaboration with Altor Locks, the GUARDIAN features the patented radial fin architecture engineered specifically to counter modern, power-tool-driven theft. Specifically designed for GEN-Y's EXECUTIVE , SPARTAN , VIKING , and NOMAD gooseneck couplers, ensuring a secure, precision-fit installation. This hitch lock is NOT compatible with GEN 2 EXECUTIVE units. It is only compatible with EXECUTIVE units that have a SnapLatch coupler. Constructed from hardened steel and equipped with a premium high-security disc-detainer core, the GUARDIAN is engineered to resist picking, cutting, grinding, and brute-force attacks. This is protection you can see and feel-heavy, solid, and purpose-built-delivering next-level security for high-value trailers and RVs. This product is engineered, assembled, and quality-controlled in Virginia by the ALTOR Lock team.
