Black Universal Trailer Hitch Lock 50mm

Trailer Hitch Lock – 50 mm Coupling | Universal Heavy-Duty Security Lock

The RBG Commercial Body Parts Trailer Hitch Lock is a heavy-duty mechanical security device engineered to provide effective theft deterrence for trailers, tow poles, and any equipment fitted with a standard 50 mm coupling. Manufactured from high-strength cast steel and finished in a high-visibility black protective coating, this lock delivers both structural durability and immediate visual deterrence.

The locking body is precision-cast to ensure close tolerance engagement with standard couplings, minimising free movement and reducing vulnerability to forced removal. A reinforced 12 mm hardened steel locking bar, formed in a rigid ring configuration, passes through the coupling mechanism and secures into the lock body via a multi-position locking system. The 8 locking positions allow controlled engagement depth and improved compatibility across varying coupling designs.

Supplied with two precision-cut keys, the lock mechanism offers reliable operation while maintaining resistance to tampering. The integrated steel construction, combined with a compact yet robust geometry, makes this unit suitable for both long-term storage and day-to-day operational use in commercial and domestic towing environments.
