The RETRUE Keyed-Alike Heavy Duty Trailer Coupler Lock Set is designed to deliver maximum trailer security with the convenience of a single-key system. Trailer theft often occurs when couplers are left unsecured, making a reliable coupler lock system essential for protecting your towing equipment.
This security kit includes two essential trailer locking components: a universal coupler lock that covers the tow ball socket and a 1/4-inch coupler tongue lock that secures latch-type couplers. With both systems working together, the trailer cannot be connected or towed by unauthorized vehicles.
The coupler lock features 11 adjustable locking positions, allowing it to fit most common trailer couplers including 1-7/8", 2", and 2-5/16" couplers. This versatility makes it ideal for use on RV trailers, boat trailers, cargo trailers, and utility trailers.
Engineered with 100% solid construction, the lock body is crafted from high-strength aluminum, while the thick A36 steel U-shaped locking bar provides exceptional resistance to cutting, prying, and impact. The reinforced structure acts as both a powerful physical barrier and a visible theft deterrent.
To ensure reliable performance in outdoor environments, the coupler lock is protected with a durable powder-coated finish, while the locking cylinder is shielded with a weatherproof rubber cap to prevent dust, moisture, and corrosion.
Security is further enhanced with an upgraded lock cylinder system and thicker precision keys, making the lock significantly more resistant to tampering or forced entry.
Because all locks are keyed alike, the included four keys operate both locks, simplifying access while maintaining high security.
Whether your trailer is parked at a marina, campsite, driveway, or storage yard, the RETRUE trailer coupler lock set provides dependable anti-theft protection and peace of mind for every towing adventure.
