AL-KO Coupler Safety Universal Lock 

Provide high-security physical protection against unauthorized hitching and trailer theft with the AL-KO Coupler Safety Universal Lock, distributed by Burquip. Engineered from a rugged cast aluminium enclosure, this heavy-duty external clamshell lock encases the ball coupling socket and handle mechanism, preventing thieves from dropping the trailer onto a tow ball while parked in driveways, storage yards, or unhitched at campsites.

Key Features & Benefits:

• Universal Coupling Compatibility: Designed to fit virtually all standard 50 mm pressed-steel and cast-iron ball couplings (non-stabiliser style) across trailers, caravans, horseboxes, and light commercial haulers.

• Heavy-Duty Cast Aluminium Shell: Robust one-piece cast body provides superior resistance against cutting, crowbar prying, and heavy hammer impact attacks while remaining lightweight and rustproof.

• Integrated Keyed Lock Cylinder: Precision-machined locking mechanism features a hardened lock core that deters picking and drilling attempts.

• Stationary Anti-Theft Defense: Completely obstructs the coupling cavity and lever motion to ensure an unhitched trailer cannot be coupled to an unauthorized vehicle.

• Weatherproof & Corrosion-Free: Cast aluminium construction will not rust, corrode, or degrade when left outdoors in harsh South African weather, coastal air, or standing rain.

• Supplied with Duplicate Keys: Includes high-security keys for multi-driver access and travel peace of mind.
