  • Premium Material: This 5/8-inch American trailer lock is crafted from high-grade carbon steel, renowned for its exceptional strength and impact resistance. Unlike ordinary steel locks that bend or fracture under stress, the carbon steel construction ensures this lock withstands road vibrations and heavy loads without deformation. The entire lock body features an electrophoretic chrome plating process, forming a dense protective layer that effectively resists rust and oxidation.
  • Universal Size: Precisely engineered at 6.6 x 0.94 inches with a 5/8-inch diameter lock cylinder and extended 4-inch effective bolt length, this trailer lock is designed to fit most trailer hitch assemblies. Specifically engineered for 2.5, 3, and 3.5-inch hitch receivers, it is compatible with Class III/IV trailer systems, catering to common configurations for large trailers, boats, caravans, trucks, and tractors.
  • Easy Installation: Installation and use of this towbar lock is exceptionally straightforward, requiring no tools or specialist skills. The locking pin features a 360-degree rotating head for easy operation. After hearing the audible click, pull the locking head again to confirm secure engagement. When unlocking by turning the key, the pin automatically springs out for convenient use.
  • Tamper-Resistant Design: This trailer lock surpasses basic protection through thoughtful engineering that enhances reliability and convenience. Its carbon steel construction, combined with an electrophoretic chrome plating process, creates a robust barrier against cutting or destruction. An integrated waterproof and dustproof cover shields the keyhole during storage, effectively preventing rain, dust, and debris from entering the lock mechanism to avoid jamming and corrosion.
  • Packaging Includes: This product is packaged in a pouch, with each set containing one premium 5/8-inch American trailer lock and two matching keys. The dual-key design offers added convenience: the primary key can be stored with your vehicle keys, while the spare key can be kept in a secure location for emergencies. This single-item kit allows you to immediately safeguard your towing equipment, serving as an efficient towing security tool.
